Burgess Shale Fossil Provides Crucial Missing Link
2013-03-14 05:05:04

April Flowers for redOrbit.com - Your Universe Online Located in Yoho National Park, Canada's Burgess Shale fossil beds have yielded yet another major scientific discovery. Scientists from the University of Toronto, the University of Cambridge, and the University of Montreal have unearthed a strange phallus-shaped creature from the 505 million year-old rock layers. The study, published in a recent issue of Nature, confirms Spartobranchus tenuis as a member of the acorn worms group....

Fossils Show Anatomy Of Ancient Fuxianhuiid Arthropod

April Flowers for redOrbit.com - Your Universe Online An international group of scientists led by researchers at the University of Cambridge has made an extraordinary find in South China. For the first time, scientists are able to see through the head of the "fuxianhuiid" arthropod, revealing one of the earliest evolutionary examples of limbs used for feeding along with the oldest nervous system to stretch beyond the head in fossil record. Prior to this find, heads covered by a...

New Ostracod Species Discovered In Ancient Fossil Record

Brett Smith for redOrbit.com - Your Universe Online A team of British and American scientists have discovered the fossils of a tiny new species of animal in 425-million-year-old rocks located along the England-Wales border, according to the their report published in the journal Proceedings of The Royal Society B. The new species is an ostracod — a small crustacean related to crabs, lobsters and shrimps — and was exceptionally well preserved. Its fossil included a...

Ancient Turtles Make Love, Embraced Death

Lee Rannals for redOrbit.com German paleontologists wrote in the Royal Society Journal Biology Letters that they have uncovered the remains of nine turtle pairs that died while having sex 47 million years ago. The scientists wrote in the report that they had determined the ancient turtles died while mating in poisonous waters. "Millions of animals live and die every year and many enter the fossil record through serendipitous circumstances, but there really is no reason to enter the...

The Burgess Shale of British Columbia is arguably the most important fossil deposit in the world, providing an astounding record of the Cambrian "Explosion," the rapid flowering of complex life from single-celled ancestors. While most of the fossil record is comprised of shells, teeth and bones, the Burgess Shale preserves the softer bits–the eyes, guts, gills and other delicate structures–of animals belonging to Earth's earliest complex ecosystems a half a billion years ago. The...

Researchers Discover Ancient Tulip-like Creature In The Canadian Rockies
2012-01-20 07:49:18

A strange tulip-shaped creature discovered in half-a-billion-year-old rocks had a feeding system unlike any other animal, researchers reported this week. Officially named Siphusauctum gregarium, the fossils, unearthed from the Middle Cambrian Burgess Shale in the Canadian Rockies, reveal a peculiar creature roughly 7-8 inches long with a unique filter feeding system. The creature has a long stem with a bulbous cup-like structure -- similar to that of a tulip -- near the top that...

Image 1 - Researchers Track Half-billion Year Old Predator

Researchers from the University of Saskatchewan and Royal Ontario Museum (ROM) have followed fossilized footprints to a multi-legged predator that ruled the seas of the Cambrian period about half a billion years ago. "Short of finding an animal at the end of its trackway, it's really very rare to be able to identify the producer so confidently," said Nicholas Minter, lead author of the article on the study, which appears in the latest issue of the Proceedings of the Royal Society B. Minter...

525-million-year-old discovery of 'feathered helmet from beyond the clouds' Researchers from China, Leicester and Oxford have discovered a remarkable fossil which sheds new light on an important group of primitive sea creatures. The 525-million-year-old fossil belongs to a group of tentacle-bearing creatures which lived inside hard tubes. Previously only the tubes have been seen in detail but this new specimen clearly shows the soft parts of the body including tentacles for feeding....

A utility company found a trove of animal fossils that dates back 1.4 million years at a building site it was working on. Researchers say the find could help fill in the blanks of Southern California's history. The area contains nearly 1,500 bone fragments, including a giant cat that was the ancestor of the saber-toothed tiger, ground sloths the size of a modern-day grizzly bear, two types of camels and over 1,200 bones from small rodents.  Researchers said that other finds include...

The remains of a strange, prehistoric saber-tooth cat have been unearthed in an ancient former rainforest in Australia, scientists said Thursday. Paleontologist Henk Godthelp, who led the discovery, said this is the first time the carnivore had been seen in Australia. He called the find an exciting and unique discovery. The animal is "sort of like a native cat with a broad flattish head with large canines," said Godthelp. "It's an animal we don't think we've seen before up at Riversleigh so...
