Scientists have found the fossilized remains of the brain of the world’s earliest known predators, from a time when life teemed in the oceans but had not yet colonized the land.
An international team of paleontologists has identified the exquisitely preserved brain in the fossil of one of the world’s first known predators that lived in the Lower Cambrian, about 520 million years ago. The discovery revealed a brain that is surprisingly simple and less complex than those known from fossils of some of the animal’s prey. (more…)
UA Regents’ Professor Nicholas Strausfeld and an international team of researchers have discovered the earliest known complete nervous system exquisitely preserved in the fossilized remains of a never-before described creature that crawled or swam in the ocean 520 million years ago.
A team of researchers led by University of Arizona Regents’ Professor Nick Strausfeld and London Natural History Museum’s Greg Edgecombe have discovered the earliest known complete nervous system, exquisitely preserved in the fossilized remains of a never-before described creature that crawled or swam in the ocean 520 million years ago.
The find suggests that the ancestors of chelicerates – spiders, scorpions and their kin – branched off from the family tree of other arthropods – including insects, crustaceans and millipedes – more than half a billion years ago. (more…)
