Ichthyosaur Birth Preserved In Fossil
2014-02-13 11:23:09

PLOS Ichthyosaur fossil may show the earliest live birth from an ancient Mesozoic marine reptile, according to a study published February 12, 2014 in PLOS ONE by Ryosuke Motani from the University of California, Davis, and colleagues. Ichthyosaurs were giant marine reptiles that evolved from land reptiles and moved to the water. Scientists report a new fossil specimen that belongs to Chaohusaurus (Reptilia, Ichthyopterygia), the oldest of Mesozoic marine reptiles that lived...

redOrbit Staff & Wire Reports - Your Universe Online Newly discovered fossilized skin pigments from a trio of multi-million-year-old marine reptiles reveal that these real-life sea monsters were at least partially dark colored when they were alive, according to research appearing in the latest edition of the journal Nature. The fact that creatures such as mosasaurs and ichthyosaurs were dark-colored is likely to have contributed to more efficient thermoregulation, while also serving...

Giant Marine Predator Fossil Unearthed In The Nevada Desert
2013-01-08 08:15:49

April Flowers for redOrbit.com - Your Universe Online In a new report, a multinational research team details the recovery of a fossil marine predator. The animal, which measured about 28 feet in length, was recovered from the Nevada desert in 2010. This fossil, found in what is today a remote mountain range, represents the first top predator in marine food chains feeding on prey similar to its own size. A major portion of the animal was preserved, including the skull, parts of the fins,...

U.S. and British scientists say they've determined the transition of extinct sea creatures from egg-laying to live-born opened up evolutionary pathways. Scientists at Harvard University and the University of Reading say they also determined the evolution of such live-born young depended crucially on the advent of genes -- rather than incubation temperature -- as the primary determinant of offspring sex. In the study of three lineages of extinct marine reptiles -- mosasaurs, sauropterygians...

Live birth -- key to much marine life -- depends upon evolution of chromosomal sex determination A new analysis of extinct sea creatures suggests that the transition from egg-laying to live-born young opened up evolutionary pathways that allowed these ancient species to adapt to and thrive in open oceans. The evolutionary sleuthing is described this week in the journal Nature by scientists at Harvard University and the University of Reading who also report that the evolution of live-born...
