230-million-year-old mites found in Dolomite amber

Scientists have found two gall mites and a fly preserved in 230-million-year-old Late Triassic amber from the Dolomite Alps in northeastern Italy. These are the first arthropods (a phylum of invertebrates including insects, arachnids and crustaceans) found in amber from the Triassic. Although arthropods appear in the fossil record starting in the Early Cambrian period around 540 million years ago, these are the oldest arthropods ever discovered trapped in amber, 100 million years older than prior examples.

Amber droplets found in Triassic outcrops of the Dolomite AlpsResearchers gathered thousands of droplets of amber no more than six millimeters long from outcrops on the Dolomites, then spent two years screening each tiny piece for any plant or creature they might contain. If you think this must have been a painfully tedious experience, you think right.

“Before preparation, one of the tiny flecks of amber, about 1 millimeter in diameter, wafted onto the floor of my lab,” [David Grimaldi, curator of invertebrate zoology at the American Museum of Natural History in New York,] recalled. “Alex Schmidt and my assistant who did the prep, Paul Nascimbene, spent about three hours on their hands and knees with flashlights. I don’t know how, but they found the speck on the floor hidden in the corner between two lab benches. It was a nerve-wracking time.”

Triassic midge fly parts, head upper leftIt’s a good thing they were that dedicated to the task, because out of the 70,000 droplets of amber they analyzed for inclusions, three of them contained the groundbreaking arthropods: one partial midge fly (Diptera) about the size of a head of a pin, and two new species of gall mites. The amber had preserved the head, antenna, four legs and some fragments of the body of the midge fly which taken together were 1.5-2 millimeters in size.

The mites were complete and far tinier. One of them, Triasacarus fedelei, is shaped like a worm and is 210 microns long. Due to its body shape and differences in the structure of the mouth, researchers believe it may be an ancestor of modern gall mites. The second mite, Ampezzoa triassica, is even smaller at 124 microns in length. Its shape is more typical of modern gall mites.

Gall mites in 230-million-year-old amber dropletsThe amber preserved these creatures so well that scientists could examine them in microscopic detail, allowing them to identify minute characteristics like tiny waxy filaments on the surface of Triasacarus fedelei’s body that are thought to have helped protect them from predators, parasites and the elements. Both mites have two pairs of legs like present-day mites.

One way in which they’re different from their modern relatives is that the Triassic mites must have fed on conifers, since it’s conifer resin that hardens into amber. Today 97% of Eriophyoidea, the group gall mites belong to, feed on flowering plants, which means the mites changed their eating and living habits entirely when the new plant species came on the scene about 140 million years ago.

Family receives soldier’s will left on a bus in 1944

In October of last year, employees at the National Express bus depot in Birmingham were clearing out the lost property office so it could be painted when they came across something that had been lost since 1944. When she moved a heavy cardboard box on top of a dusty old metal cabinet, Christine McDaid found an old war office envelope. Inside she found the last will and testament of Private Gordon Albert James Heaton of Handsworth, Birmingham, and a letter from the war office dated November 1944 asking his family about his estate.

The official envelope was still sealed, which means in all likelihood these documents had never reached their destination 67 years ago. They were probably left on the bus by the courier. In attempt to ensure the family finally received this sad and important part of their history, National Express put out a press release about the find. The story was picked up by the BBC at the time.

While they waited for a response, Christine McDaid did some research on Private Heaton and found that he had been killed in France in August of 1944, less than two months after he made the will. He was 21 years old. Heaton was a member of the 1st Battalion Worcestershire Regiment who took part in the River Seine Crossing at Vernon between August 26th and August 28th, 1944. This was the final Allied push chasing retreating German troops out of Normandy. Private Heaton was killed in the advance on Tilly on August 27th and was buried at the Vernonnet Cemetery outside of Vernon along with 15 other members of his regiment.

This month, David Hall was researching his family history when he came across the story about Private Heaton’s will on the BBC website. Hall’s 80-year-old great uncle John Heaton is sick in the hospital and David has been visiting him. He got the idea to look for information about his uncle’s long-lost brother Gordon who they thought had died during the war. When he searched for “Private Gordon Heaton” he found the story about the will. He knew the name alone wasn’t enough information to be certain it was the same person, but he contacted National Express and did further research. War department records confirmed that the will was indeed the last testament of the great uncle he never knew.

In a sad coincidence, the Heatons never received the war office telegram informing them of their son’s death. Then months later, the will, as we know, was left on a bus, so they never received anything official notice that Gordon was dead at all. They just assumed he had died when the war was over and he didn’t come back.

Last week, Christine McDaid returned the documents to David Hall who accepted them gratefully in his great-uncle’s name. John Heaton has not yet been told about this momentous find as the family believes he is too ill at the moment to take it in, but when his health improves they will have his brother’s final testament to show him.

Historic Green-Wood Cemetery vandalized

Shattered headstone of McNeil graveBrooklyn’s historic Green-Wood Cemetery was brutally vandalized the night of Monday, August 20th. Grounds workers discovered during the course of their duties Tuesday morning that at least 43 memorials, monuments and gravestones had been intentionally damaged. Some of the damage was minor, disrespectful but fixable with a cleaning. Much of it was considerably more severe, ranging from a trampled 19th-century American flag to shattered headstones. The total estimated cost of repair is more than $100,000.

Urns were cracked and pushed off their bases. Four marble crosses were toppled; three of them broke into pieces.

Two memorial porcelain photographs of the deceased were scratched repeatedly; another was smashed with a rock. Three gravestones were smeared with mud. And, this: a trash receptacle rolled down a hill, two stop signs were folded in half, and a Toro Workman cart was pushed up an embankment in an apparent effort to turn it over.

Vandalized Law family plotsThree headstones in the Law family plot were knocked over. The mausoleum of the Bourne family, designed by Beaux-Arts architect Ernest Flagg, had one of a pair of classical stone vases framing it toppled and broken in two. The cemetery is in the process of contacting family members of all the vandalized graves, but it’s taking some time to reach the families of people who died in the mid-19th century. Their contact information is not current, needless to say.

Decapitated angel from the tomb of Dwight Abbey, died at 5 years oldAlthough Green-Wood, like most cemeteries, has dealt with vandalism before, it has excellent security. The 478-acre grounds are surrounded by a high cast iron fence; there are video cameras all over the park and a car patrol that operates 24 hours a day. A possible suspect was captured on video. The recording has been handed over to the NYPD Hate Crime Task Force which is investigating the case.

The cemetery has already begun making repairs and will foot the bill, but they are asking for donations to help defray the cost. Click here if you would like to contribute.

Established in 1838, Green-Wood was one of the first garden cemeteries in the country. Spacious burial grounds set in a landscaped park-like environment on the outskirts of a city were a reaction to the increasingly crowded urban churchyards which were often putrid, poorly guarded and vermin-infested. Old remains in such places had to be regularly disinterred to make room for new ones since there was little room for expansion.

Père Lachaise Cemetery in Paris was the first garden cemetery established in 1804. The first one in the United States was Mount Auburn Cemetery outside Boston in 1831. Its pastoral vista of rolling hills with classical monuments, bodies of water and groves of trees had the appeal of an English garden, then a popular landscaping trend. It was also non-sectarian, unlike the churchyards which determined who could be buried in them based on their religious affiliation.

Gothic revival entrance to Green-WoodSo beautiful and peaceful were the new garden cemeteries that they become popular tourist attractions. People would make a day of it and picnic on the grounds. These wide-open pastoral spaces for the dead inspired the creation of wide-open pastoral spaces for the people still living in the city, hence the construction of Central Park in New York City.

In the late 19th century, Green-Wood was the premiere burial ground for the rich and famous of New York. It also provided eternal rest to Civil War veterans, including ones who couldn’t pay, and to the victims of tragedies like the Brooklyn Theater Fire of December 5th, 1876.

Some of Green-Wood’s 560,000 permanent residents include composer Leonard Bernstein, several Roosevelts, newspaper publisher Horace Greeley, Lola Montez (the dancer and courtesan whose charms brought down King Ludwig I of Bavaria), pioneering journalist Nellie Bly who famously beat Jules Verne’s fictional Phileas Fogg to go around the world in a record 72 days, Louis Comfort Tiffany and Boss Tweed.

There are some lovely pictures of the cemetery today and in years past on Green-Wood’s Flickr photostream. Even today it’s a tourist destination, known not just for interesting themed tours of its permanent residents, but also for its excellent bird-watching and as a Revolutionary War battlefield (the Battle of Long Island was fought there).

Experts dig under parking lot for Richard III’s grave

King Richard III, painter unknown, ca. 1590-1610King Richard III, last Plantagenet king of England and the last king of England to die in battle, was buried exactly 527 years ago on August 25th, 1485. Today, on the anniversary of his burial, archaeologists from the University of Leicester will try to dig him up again. It’s the first archaeological excavation ever to search for the lost grave of a British sovereign.

It’s all the Tudors’ fault, of course. Henry Tudor’s Lancastrian troops defeated Richard’s Yorkist army at the Battle of Bosworth Field on August 22, 1485. Richard died on that field, felled by blows to the head from a poleaxe. With Richard’s death, Henry Tudor became King Henry VII. One of his first acts as monarch the day after the battle was to bring Richard’s body to nearby Leicester where it would be exposed, naked, and then hanged for all to see so there would be no question that the old king was dead.

Richard III falls at Bosworth; Shakespeare Window in Southwark Cathedral, designed by Christopher Webb, 1954After two days of being subjected to public ignominy, Richard’s body was buried at Leicester’s Church of the Franciscans, aka the Greyfriars. After years of dynastic dispute, the new king certainly wasn’t going to have the one he considered a usurper buried in kingly pomp with his ancestors in London, so instead the friars buried him unceremoniously in their abbey. Ten years later, Henry’s guilty conscience gnawed at him enough that he would spend £50 to have an alabaster memorial monument built over Richard’s tomb.

Then came the second Tudor Henry. Henry VIII split with the Catholic Church and the violent dissolution of the monasteries that followed did not spare Greyfriars. In November of 1538, the Greyfriars abbey and church in Leicester was destroyed. There is no record from that time describing what happened to Richard’s tomb and remains. The popular legend is that his tomb was smashed to bits and Richard’s body was taken by a mob and thrown in the River Soar. The earliest source for that story comes from mapmaker and historian John Speede writing seventy years after the purported events, however, and people who certainly would have written about it in the interim had it happened never mention a desecrating mob.

In fact, according to Christopher Wren, father of the famous architect, in 1612 there was a new monument over Richard’s grave. The property where the monastery once stood had been purchased by Leicester’s former mayor Robert Herrick who built an elegant house and gardens on the site. On the spot where the tomb of the king had been, Herrick erected a pillar inscribed, “Here lies the body of Richard III, some time King of England.” Wren worked as a tutor to Herrick’s nephew at that time and saw the monument while walking the grounds with Robert.

Richard III Society plaque on Grey Friars StreetAs the centuries passed, development entirely changed the cityscape and the exact location of Greyfriars church was lost, although the neighborhood was known. (There’s a street in the area conveniently called Grey Friars Street.) The Richard III Society put a plaque on a building to mark one potential spot.

A recent archaeological survey on Grey Friars Street done when a 1950s structure was being demolished to make way for new construction cast a whole new light on the question of where the church had been. It was a case of the dog barking in the night. The dig was in the center of the Greyfriars location, but archaeologists found nothing but a small piece of stone coffin lid. If the church had been there, they would have found much more evidence of its presence. This non-discovery discovery moved the epicenter of the Greyfriars site considerably to the west, an area that has more parking lots than real estate.

John Speede map of Leicester county and city, 1616Another recent discovery that boosted the odds of finding Richard’s burial was made by genealogist and Richard III expert Dr. John Ashdown-Hill. While researching his book The Last Days of Richard III, Ashdown-Hill examined the maps John Speede had made when he searched for Richard’s grave. He found that Speede had been looking at the wrong monastery, Blackfriars instead of Greyfriars.

Armed with this new information, University of Leicester experts used map regression analysis (a systematic comparison of different kinds of maps from different eras) to pinpoint the most likely site of the former Greyfriars church. It’s a parking lot used by the Leicester City Council.

Leicester City Council parking lotThe parking lot was surveyed Friday with ground-penetrating radar, and several archaeological hot spots were identified. Today the excavation begins. Guided by the GPR data, the archaeological team plans to start digging two long trenches.

The trenches will run North-South and should intersect with the church’s East-West walls (helpfully, Christian churches are usually built on the same alignment). The ULAS team shouldn’t have to dig too deep as, although there are hundreds of years of remains to get through, the actual strata are fairly shallow. Previous Leicester excavations have shown that the Roman layer is less than a meter down – and if you reach that, you’ve gone way past 1485.

The excavation will continue for two weeks. No visits to the dig will be allowed because the parking lot is for Council employees only, and it’s not in a publicly accessible area under normal circumstances. The weekend of September 8th, however, the site will be opened to the public. Come Monday the trenches will be filled back in and a week later it will be a parking lot again.

Archaeologists are very cautious in their estimates of what they might find. Fragments of an alabaster tomb would be nice; human remains of a male of proper age bearing evidence of fatal battle wounds would be ideal. Since time is very limited, they won’t be able to excavate any remains that aren’t likely Richard candidates, and given that churches and abbeys were thick with burials inside and outside the buildings, they could well encounter an embarrassment of options.

Michael Ibsen swabs his cheek for his royal DNAIf by some freakish good luck they do find remains that could be Richard’s, DNA experts will attempt to match its mitochondrial DNA to that of a direct descendant down the female line of Richard’s sister, Anne of York. Dr. Ashdown-Hill traced this unbroken matrilineal genealogy to Mrs. Joy Ibsen, an English-born journalist who had emigrated to Canada in her 20s. She was in her 80s when Ashdown-Hill found her and was highly amused to discover she was a 16th generation niece of Richard III. Mrs. Ibsen has since passed away, but her son Michael, a furniture-maker who lives in London, gave a swab of his precious mtDNA to the project. He was also present on Friday when the University of Leicester team explored the parking lot with ground-penetrating radar.

The last XXIV hours of Pompeii on Twitter today!

Pliny the Elder's first tweet

Today is the 1933rd anniversary* of the eruption of Vesuvius that destroyed the cities of Pompeii and Herculaneum. Starting at 8:00 AM MT, Pliny the Elder will tweet the eruption live just as it all went down.

FOLLOW HIM!

I felt this was a fitting occasion for my first tweet, which was actually a retweet. It’s a little strange and offputting, but then again, so are tremors in the earth and a Vulcan’s forge inside a mountain belching smoke.

Twitter Pliny is a feature of the Denver Museum of Nature & Science’s A Day in Pompeii exhibit which runs from September 14th, 2012 to January 13th, 2013. They have some neat companion events for children and adults, from a toga party to lectures by volcanologists.

Click to follow Pompeii's last XXIV hours!

*According to traditional dating based on a letter Pliny the Younger, nephew of the elder Pliny who was visiting his uncle on that fateful day, wrote to the historian Tacitus describing the events 25 years later. Archaeological evidence suggests the eruption took place later, sometime in November. A second letter from Pliny to Tacitus puts the date at November 23rd.

SPOILER ALERT: Here are Pliny the Younger’s letters to Tacitus. Do not read if you want to be surprised by Twitter Pliny’s live updates.
