Spawn season

I’ll start to regularly post photos of Lebanese fossils alongside links to charities supporting the thousands displaced in this war. Even the smallest donations can save lives

Cover of the journal Nature, featuring the head of a large fish with its mouth open. A smaller fish is swimming into its mouth. The cover reads "Caught in Time: Early fossils shed light on the origins of bony fish."

Osteichthyans--the bony fishes--are by far the most diverse group of living jawed vertebrates. Two papers out today in @nature.com feature remarkable new Chinese fossils that paint a picture of substantial morphological diversity among stem osteichthyans.

The oldest articulated bony fish from the early Silurian period - Nature A tiny, articulated, near-complete osteichthyan from the early Silurian Chongqing Lagerstätte, represents the oldest osteichthyan occurrence including microfossils, and the earliest articulated remain...

The second reports a tiny (~3 cm) articulated fish from the early Silurian. The material is challenging, but it is unquestionably a bony fish. Fittingly named Eosteus, it co-occurs with the oldest articulated jawed fishes and cements the antiquity of osteichthyans.

Last night I was down a rabbit hole of why fish can't exist deeper than around 8000 meters and I realized that the deepest a fish has ever gone in the ocean and survived was in a submersible. The fish were people. All vertebrates are fish.

I hope this helps with ~~the horrors~~

#ISELV #ISELV19 #ISELVUppsala

This February, the Uppsala team attended and presented at the 18th ISELV in Berrechid, Morocco, sharing our research with the global early vertebrate community #ISELV18 @iselv18.bsky.social

Following on from our post yesterday, we are honoured to announce that we will be hosting the 19th International Symposium on Early and Lower Vertebrates (ISELV) meeting here in Uppsala in 2027!

“awful people don’t deserve to be killed, but they don’t deserve to be praised, either” is apparently a thought too complex for the pundit mind

palaeontologists digging for fossils in soft sand

A team from our lab recently joined fieldwork organised by the University of Latvia, helping to excavate fossils from the Devonian, including armoured fish (Placoderms) and early tetrapods in western Latvia.

Sign the Petition Support a New Dinosaur Museum and Science Park on the Isle of Wight

Subject close to my heart - finding an ammonite on the Isle of Wight as a 6 year old started my love of geology / earth history. The Island has an incredible fossil wealth and really deserves world class facilities to display and project on the world stage! chng.it/kQKV2mLQdZ

Fossil(and more?) Friday. The Staruni Woolly Rhino was incredibly preserved with its skin in a condition good enough to be taxidermied. Her horns, hooves, hair, and guts were all that was lost, but you can see the individual follicles in her skin. #fossilfriday #EAVP2025 #MuzeumPrzyrodnicze

Thank you!

Earliest amniote tracks recalibrate the timeline of tetrapod evolution - Nature Analysis of a fossil trackway from the earliest Carboniferous of Australia shows prints of toes with claws, suggesting that the origin of amniotes was at least 35–40 million years earlier than pr...

When it comes to understanding when animals first walked on land, finding footprints of animals that literally pressed their feet into the ground absolutely holds the key.

Out Now in Nature! Amniote tracks from Australia push the timeline for terrestiality back 35 to 40 million years, with implications for our understanding of tetrapod evolution.
