My 25 years of palaeoart chronology...

A 2023 illustration of a Tyrannosaurus rex taking a bite out of an Edmontosaurus (there is fossil evidence of this, & the hadrosaur survived), from DINOSAUR BEHAVIOUR, by Prof Michael Benton (published by Princeton University Press).

Palaeontologists look at bones which to us look just like a rock, but they see a fossil. The problem is that bone fragments can be very fragile and so are difficult to establish the creature that they came from. But DNA is helping! But even DNA can deteriorate, so what then! Scientists have found that examining the short chains of amino acids found in ancient bones can help to determine the species.

One way to track what’s happened on Earth during past periods of drastic climate change is to examine fossils, but, says @KnowableMag, “the fossil record for most species is spotty.” Enter planktonic foraminifera, a unicellular marine organism that first appeared on Earth about 100 million years ago. Nine out of 10 species went extinct when an asteroid hit 66 million years ago. It took 10 million years for species diversity to recover. Tim Vernimmen takes a look at what that can teach us about the past — and future.

🐂#LostBones #FossilFriday 🦥Another huge historical museum in Minnesota! The Pine County History Museum in Askov occupies an entire former high school, features its own café, and even houses a full-sized replica of the Wright brothers' airplane. The lone Bison occidentalis skull pictured has a 79cm horn core span. It was unearthed by the Alexander Construction near a creek in Pine County - May 1968.
