[Geology2] The Ichthyosaurs survived longer than was thought

I love when that happens . . .

The Ichthyosaurs survived longer than was thought
PhysOrg.com [USA],January 5, 2012

The discovery of a new species of ichthyosaurs considerably changes our
understanding of the evolution and the extinction of these dinosaur age
sea reptiles, according to a study published this week in PLoS ONE by an
international team of Belgian, British and German scientists. This work
shows that the ichthyosaurs were not subject to a major extinction at
the end of the Jurassic era (145 million years ago). It furthermore also
shows that the ichthyosaurs remained very diversified until their
definitive extinction, around 94 million years ago.

Prehistoric predators with supersized teeth had beefier arm bones
PhysOrg.com [USA], January 4, 2012

The toothiest prehistoric predators also had beefier arm bones,
according to results of a study published today in the journal
Paleobiology. Saber-toothed tigers may come to mind, but these extinct
cats weren't the only animals with fearsome fangs. Take the false
saber-toothed cats -- also known as nimravids -- and their catlike
cousins, a family of carnivores called the barbourofelids. These mammal
groups lived millions of years before cats came to be, and had
knife-like canines along with well-built arm bones, said Julie Meachen,
a paleontologist at the National Science Foundation (NSF)
NationalEvolutionary Synthesis Center (NESCent) in Durham, North
Carolina.
