Ancient Eel-Like Chordates Linked To Evolution Of Human Skeleton
2013-10-17 07:59:04

redOrbit Staff & Wire Reports - Your Universe Online An international team of paleontologists has published new research in the journal Nature revealing that the human skeleton did not evolve from ancient predatory fossil fish, as previously believed. Rather, the human skeleton evolved as a way to protect against predators such as the conodont, extinct eel-like chordates that evolved tooth-like structures and tissues independently of other creatures, according to experts from...

The tiny teeth of a long-extinct vertebrate — with tips only two micrometers across: one twentieth the width of a human hair — are the sharpest dental structures ever measured, new research from the University of Bristol and Monash University, Australia has found. For 300 million years, Earth´s oceans teemed with conodonts — early vertebrates that kept their skeleton in their mouth.  The elements of this skeleton look uncannily like teeth (see image) and, like...

A fang-like tooth on double upper lips, spiny teeth on the tongue and a pulley-like mechanism to move the tongue backwards and forwards "“ this bizarre bite belongs to a conodont and, thanks to a fresh fossil find, has now been analyzed and reconstructed by a Swiss-French research team headed by paleontologists from the University of Zurich. Their analysis sheds some light on the evolutionary origin of jaws. Using a 3D animated model, the reconstruction shows for the first time how the...

Spanish researchers have found fossils of Ordovician conodonts dating to between 446 and 444 million years ago for the first time in the western Mediterranean. The discovery of these very primitive marine vertebrates has helped scientists to reconstruct the palaeogeography of the Cordillera B©tica mountain range. Their study shows that the mountain system in the south of the Iberian Peninsula was located alongside the Alps at that time. In 2006, a group of Andalusian geologists found the...

The mystery of how an abundance of fossils have been marvelously preserved for nearly half a billion years in a remote region of Africa has been solved by a team of geologists from the University of Leicester's Department of Geology. They have established that an ancient wind brought life to the region "“ and was then instrumental in the preservation of the dead. Sarah Gabbott, Jan Zalasiewicz and colleagues investigated a site near the Table Mountains in South Africa. Their findings...

Reconstructing ancient fossils from hundreds of thousands of jumbled up pieces can prove challenging A new study pitting academic expertise against a computer in recreating a 425 million-year old jigsaw puzzle has discovered that there is no substitute for wisdom born out of experience. The research tested the reliability of expert identification versus computer analysis in reconstructing fossils. The investigation, based on fossil teeth from extinct vertebrates, found that the most...

A paper in this week's PLoS Biology reports that a common gene regulatory circuit controls the development of all dentitions, from the first teeth in the throats of jawless fishes that lived half a billion years ago, to the incisors and molars of modern vertebrates, including you and me. "It's likely that every tooth made throughout the evolution of vertebrates has used this core set of genes," said Gareth Fraser, postdoctoral fellow at Georgia Tech's School of Biology. The first vertebrates...
