My first ideas to the finished "sea-rex" artwork; commissioned by The Etches Collection, which is where the spectacular pliosaur's skull is exhibited. Also pictured is a smaller "sea-rex" and Thrissops fish.

Primatologist said in interview released after her death she would also put Putin, Xi and Netanyahu on that spaceship In a lifetime studying the behavior of chimpanzees, Jane Goodall became something of an authority on the aggressiveness of alpha male adults. Now, in an interview released just days after her death, the famed primatologist reveals what she would do with Donald Trump, Elon Musk and other human beings she saw as showing similar traits: launch them on a one-way trip into space. The insight into Goodall’s thinking comes in the Netflix documentary Famous Last Words, recorded in March and kept under wraps until her death last week at the age of 91. Continue reading...

One year ago today, critters began roaming through Panjura and Gondwa free from their burrows, looking out for danger and hunting for prey.

What is your favorite roaming critter? Is it a friend or a delicious snack?

Portrait of Tameryraptor markgrafi, a carcharodontosaurid from the Late Cretaceous of Bahariya Formation (Egypt). Its remains have long been attributed to Carcharodontosaurus, but it is distinguished by the presence of a small horn on its nose and symmetrical teeth.

We have a new paper out! Turtle ancestors evolved a shell—but what else? We found that an unique rostral vasculature was also obtained gradually along the lineage, and that one of the earliest turtles Proganochelys likely retained a mostly ancestral state!🐢 sjpp.springeropen.com/articles/10....
