Jurassic Undertakers Feasted on Dead Dinosaurs

Dermestid beetles are well known in forensic circles: They congregate on corpses to feed and breed, and their presence and life stage can help establish when the victim died. Some species haunt natural history museums, where they can be pests (munching the dead skin of stuffed animals) or helpers (enlisted by curators to clean bits of tendon and muscle off skeletons).

Now, new evidence shows that dermestids were recycling carcasses as far back as the Jurassic.

Working with two collaborators, Brooks B. Britt of Brigham Young University in Provo, Utah, examined the 150-million-year-old fossil of a Camptosaurus dinosaur and observed that most of its bones bear minute pits, grooves, bores, and scratches. Those, the team established, are the telltale signs of dermestid larvae that tried to get at the bone marrow after the putrid dinosaur meat ran out.

The marks matched those made by modern-day dermestids and not those of any other insect scavengers, such as termites (which can consume an entire human skeleton), mayfly nymphs, or moth larvae.

After examining 7,000 fossilized bones in addition to the Camptosaurus’s, Britt says insect marks are common but often go unnoticed. Insect activity could explain some fossil mysteries, such as “dinosaur dentures” — teeth that are found side by side in perfect order but without any supporting jaw. Chances are, scavenging insects ate the whole bone away before it could fossilize.

The finding was detailed in the journal Ichnos.

January 2011: The humble ginger root could be the key to conserving the UK’s largest and most spectacular terrestrial beetle – the stag beetle. Ecologists from Royal Holloway, University of London and the University of York have developed a series of new methods to monitor stag beetle numbers – including ginger lures to trap adult beetles and tiny microphones to detect sounds made by the larvae in their underground nests. Conservation efforts have been hampered until now because ecologists lacked a reliable way of monitoring stag beetle numbers: here.

Most US allies in Iraq to pull out troops

Wednesday, Sep 10, 2008

The number of countries fighting in the US-led coalition in Iraq is set to fall to a “handful” over the next three months, according to a senior US official. …

The US official said that most of the 29 countries fighting alongside American and Iraqi forces would withdraw their troops this year. …

Georgia pulled out its 2,000 troops last month during its own conflict with Russia. The UK, the second-largest contributor to the coalition, still has about 4,000 troops in Iraq. …

US commanders in Iraq have called for about an additional 10,000 troops to help quell the insurgency.

26 pearls found in Lebanese oyster


This video is called Oyster Fishing at Whitstable, England (1920).

From the Herald Sun in Australia:

One oyster yields 26 tiny pearls

From correspondents in Tyre, Lebanon

September 09, 2008 10:13pm

A LEBANESE woman working in a restaurant kitchen found 26 pearls in an oyster she was preparing for the table and will submit the find to the Guinness Book of Records.

Amal Salha, 50, said she was helping out her son in his Al Fanar restaurant on the waterfront in the southern port of Tyre, when she made the astonishing find yesterday evening.

“I couldn’t believe it,” she said.

“I was in the process of opening the shells when I found a number of shining pearls inside one of them,” she said. “I was so startled I screamed.

“It was so beautiful. It looked like a bunch of grapes.”

After counting them, there turned out to be 26 pearls of varying sizes. The oyster had been harvested off the Lebanese coast.

Pearl oysters are unrelated to the oysters normally eaten in Europe but Mrs Salha said they were still popular with the French and Italian soldiers serving with the UN peacekeeping force deployed in south Lebanon.

“We buy these oysters at $US10 ($12.26) dollars a kilo,” said Mrs Salha’s husband, Raymond.

“Generally we find one or two pearls but 26 is very rare.”

South Africa: Leopard Toad’s Trek Ends in Death on the Road

Cape Town

So near and yet so far. After an epic journey of 3,5km that involved crossing some of Cape Town’s busiest highways, Big Mamma made it to within 200m of her vital breeding destination – only to be flattened by a vehicle at the last moment.

Big Mamma was an endangered Western Leopard Toad (Amietophrynus pantherinus) which had been living in the conservation area in the centre of Gold Circle’s Kenilworth racecourse.

She was originally found in a private garden in nearby lower Wynberg, but was transferred to the reserve earlier in 2008 because she would be safer there.

Maya Beukes, reserve manager at Kenilworth, was delighted, because although there were records of this species in the area, very few had been seen in recent years and the location of their breeding sites were unknown.

By fitting Big Mama with a small tracking device and monitoring her movements more closely, conservation staff hoped to find out more about the toad population and so ensure their long-term survival in the Kenilworth area.

The toad was kept in captivity for about three months while tracking devices were imported from Britain. During this time, she began to fill with eggs.

Last month, the device was fitted on her back and she was released in the centre of the racecourse conservation area.

For several nights she was released and recaptured and then released again to determine whether her movements were calculated, habitual or random, said Beukes.

Each time Big Mamma was released, she headed in the same direction, “which means that she managed to calculate exactly where she had to go”.

And she was apparently determined to reach her destination, travelling between 500m and a kilometre each night – at between one and two metres a minute – through very rough, uneven and overgrown fynbos and kikuyu terrain.

“She crawled, climbed and conquered obstructions that had been previously believed to be impermeable to adult toads,” said Beukes.

After her final release, Big Mama made her way across the racecourse, over both sets of three lanes of the M5 highway, across the degraded Youngsfield military base and then across busy Ottery Road.

“She was making her way down towards the Royal Cape Golf Club, where we’d already identified two breeding sites, when we lost her signal,” said Beukes.

“We searched desperately for her for three days before we found her on the third night.

“Unfortunately, Big Mamma didn’t make it to her breeding site to find a mate and release her eggs.

“She was found flattened by a car in the middle of a small side road bordering the golf club, only about 200m from her probable breeding site.

“Her story highlights the plight of the Western Leopard Toad and the incredible danger that this species faces,” said Beukes.
