Record-busting scorpion was bigger than man

Paris: This was a bug you couldn’t swat and definitely couldn’t step on. British and German researchers reported Wednesday that they had discovered the giant fossilised claw of an ancient sea scorpion that, hundreds of millions of years ago, would have been over 8 feet long - much taller than the average man, and almost as long as a car.

The find, in a quarry near the German town of Pruem, is the biggest specimen of arthropod ever found, they said in a study published by Biology Letters, a journal of Britain’s Royal Society.

“This is an amazing discovery,” said Simon Braddy, from the University of Bristol in England.

“We have known for some time that the fossil record yields monster millipedes, super-sized scorpions, colossal cockroaches and jumbo dragonflies, but we never realised until now just how big some of these ancient creepy-crawlies were”


The 18.4-inch claw was wielded by a species of sea scorpion called the Jaekelopterus rhenaniae, which lived between 460 and 255 million years ago.

Using the claw as a benchmark, the scientists believe its owner was between 7.57 and 8.41 feet long.

Chelicerae - wand-like appendages used to grasp food and bring it to the beast’s mandibles - would have added another 1.6 feet.

“This exceeds the previously-recorded maximum body length of any arthropod by almost half a metre, the chelicerae not included,” their study says.

Despite their name, sea scorpions, known as eurypterids, were not true scorpions. Equipped with long, flat, jointed carapaces, they stalked warm shallow sea waters from around 500 million to 250 million years ago, eventually moving into fresh water.

Biologists delving into Earth’s distant past are divided as to how some arthropods were able to develop into such monstrous size.

Some suggest that they benefit from an oxygen-rich atmosphere, while others argue that they had to get bigger in order to keep up with the super-sizing of their likely prey, the early armoured fish.

“There is no simple single explanation,” said Braddy. “It is likely that some ancient arthropods were big because there was little competition from the vertebrates, as we see today. If the amount of oxygen in the atmosphere increased suddenly, it doesn’t mean all the bugs would get bigger.”

Ancients knew chocolate was good

Residents of Central America were enjoying chocolate drinks more than 3,000 years ago, a half millennium earlier than previously thought, new research shows.

People were drinking chocolate in Central America more than 3,000 years ago, scientists say.

Archaeologists led by John Henderson of Cornell University studied the remains of pottery used in the lower Ulua Valley in northern Honduras about 1100 B.C.

Residue from the pots contained theobromine, which occurs in the cacao plant and is the source of chocolate, the researchers said in Monday's online edition of Proceedings of the National Academy of Sciences.

The find dates the first use of chocolate to some 500 years earlier than previously known, they said.

The style of the pottery indicates that cacao was served at important ceremonies to mark weddings and births, according to the authors.

Prawns do feel pain, say scientists

Tucking into a plate of seafood, few diners spare a thought for the feelings of the creatures in front of them.

Scientists have no qualms either, having long argued that crustaceans such as lobsters don't feel pain even when cooked live in boiling water.

But a British biologist is challenging this orthodoxy with a study suggesting that prawns, at least, do suffer when harmed.

Professor Robert Elwood dabbed acetic acid, the main ingredient of vinegar, on to the antennae of 144 of them.

The prawns reacted by rubbing the affected parts of their bodies for up to five minutes.

The reaction, he said, was exactly the same as that seen in mammals exposed to painful irritants.

"The prolonged, specifically directed rubbing and grooming is consistent with an interpretation of pain experience," he told New Scientist magazine.

Most biologists believe that simple invertebrates - animals with no backbones and limited nervous systems- cannot feel pain or experience-suffering.

Professor Elwood, of Queen's University, Belfast, rejects this argument on evolutionary grounds. The ability to suffer allows animals to learn from harmful experiences and avoid them in the future, he said.

His research has not, however, convinced other experts in the field.

Liverpool University's Dr Lynne Sneddon, who has investigated whether eels feel pain, said: "You could argue the shrimp is simply trying to clean the antenna rather than showing a pain response."

Dr Richard Chapman, of the University of Utah's pain response centre, said there was a difference between responding to an acidic chemical and actually feeling pain.

Most animal have sensors that react to irritants, he said, adding: "Even a single-cell organism can detect a threatening chemical and retreat from it. But this is not sensing pain."

Annette Pinner, of the Vegetarian Society, said diners should avoid eating lobsters even if the jury was still out on whether they can suffer.

She added: "The more information people have about the pain that animals feel and the way they are treated, the more likely they are to move to a vegetarian diet."

A new speed record, but not a good one

Olympique Lyon's Czech forward Milan Baros was caught speeding at 168 miles per hour in his Ferrari, a club source confirmed Friday.

Local newspaper Le Progres quoted police as saying the former Liverpool player had broken the record for speeding for that French region, set by a motorcyclist who reached 154 mph in 2000.


Baros was driving on a motorway not far from Lyon on Thursday when he was caught by French police, who confiscated the black Ferrari and took his driving license.

The 26-year-old, sidelined by an injury, had to take a taxi back to Lyon. He faces a heavy fine and a three-year driving ban.
