New paper out in @jvertpaleo.bsky.social! With a team led by @barankarapunar.bsky.social, we report an Early Triassic marine vertebrate assemblage from the 🇮🇹 Dolomites that includes a possible saurosphargid, one of the earliest records of the group in the world! 🐢 www.tandfonline.com/doi/full/10....

It’s common to say the joy of finding a fossil is being the first person to see something, but I’ve never felt that way. It’s connection. They were here. Right here, where I am. Across millions of years, owing a lot to chance, we came into contact because we’ve shared the same planet. I love it.

If you will listen to this episode, keep in mind that the odds that an early Triassic ichthyosaur bigger than an orca or what we know so far are not that bad.. and that this thing was hungry too

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.
Portrait of Mary Anning wearing a green cloak and straw bonnet, holding a hammer and with a basket over her arm.Extract of a letter from Elizabeth Philpot to Mary Buckland about Mary Anning: 'yesterday she had one of her miraculous escapes in going to the beach before sunrise and was nearly killed on passing over the bridge by the wheel of a cart which threw her down and crushed her against the wall, fortunately the cart was stopped in time to allow of her being extricated from her most perilous situation and happily she is not prevented pursuing her daily employment.'Early 20th century postcard showing the bridge (circled) where Mary Anning had her accident on 8 December 1833. The Fossil Depot to the right of the bridge had nothing to do with Mary Anning and was demolished with other buildings on that side of the bridge to widen the road in 1913.

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 :) #PrehistoricPlanetIceAge

Observations on #PrehistoricPlanetIceAge: 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.
