9 December 1833: In Lyme Regis Elizabeth Philpot writes to Mary Buckland in Oxford to tell her that Mary Anning was almost killed by a cart on the narrow bridge over the River Lym as she was heading for the beach before dawn. This was one of at least 6 occasions when Mary narrowly escaped death.

Very excited to share that our latest paper is out in Science! We show that the type specimen of Nanotyrannus—an isolated skull—is fully grown, showing that it is not a juvenile Tyrannosaurus rex but a distinct species (1/12)

Yes, there was a deliberate push to get rid of all scientific names; of course, I think this is a massive mistake. And, indeed, no roaring for sabretooths, their hyoid anatomy indicates that they couldn't do it :)

Observations on

: wonderful, of course. But a strange reluctance in narration to a) state where in the world a scene takes place and b) use genus names. Odd, since no such reluctance in the Mesozoic series.

If there is anything that excites me as much as diplodocid to study, it probably would be a big cat or machairodontid. And using a quote by a TV host to answer about other mammals ''This is brilliant! But i like this.'' Hope to see more cats in different exhibitions (and maybe outside of museums)
