[ Watch the Video: Two Turtle Bones Reunited After 160 Years ] Brett Smith for redOrbit.com - Your Universe Online Against insurmountable odds and after more than 160 years, an ancient sea turtle has finally been reunited – with itself. Fossil evidence of the massive turtle Atlantochelys mortoni was first discovered in 1849 in the form of one-half of an upper arm bone – called the humerus. The other half of that bone would lie in a New Jersey streambed until it was stumbled upon...

April Flowers for redOrbit.com - Your Universe Online Describing life in the Devonian period in what is now northern Canada, Dr. Ted Daeschler of Drexel University said, "We call it a 'fish-eat-fish world,' an ecosystem where you really needed to escape predation.” The famous fossil fish species Tiktaalik roseae lived in this environment 375 million years ago. Daeschler, associate professor at Drexel University in the Department of Biodiversity, Earth and Environmental Science,...

  The Academy of Natural Sciences today announced the discovery of a new species of large predatory fish that prowled ancient North American waterways during the Devonian Period, before backboned animals existed on land. Drs. Edward "Ted" Daeschler and Jason Downs of the Academy and colleagues from the University of Chicago and Harvard University describe the new denizen of the Devonian they named Laccognathus embryi in the current issue of the Journal of Vertebrate Paleontology....

Now, new research is providing the first glimpse at the internal head skeleton of Tiktaalik roseae. The transition from aquatic to terrestrial lifestyle involved complex changes not only to appendages (fins to limbs) but also to the internal head skeleton, researchers report in the recent issue of the journal Nature....

LONDON -- Scientists have caught a fossil fish in the act of adapting toward a life on land, a discovery that sheds new light one of the greatest transformations in the history of animals. Scientists have long known that fish evolved into the first creatures on land with four legs and backbones more than 365 million years ago, but they've had precious little fossil evidence to document how it happened. The new find of several specimens looks more like a land-dweller than the few other fossil...
