A stunner of an Archaeopteryx fossil preserves SO MUCH soft tissue, including scales on its toe pads and a group of flight feathers never seen before in Archaeopteryx. Called tertials, they lie between the elbow and the body, and play a key flight role in modern birds.

In my latest for CNN, lead study author and paleontologist Jingmai O'Connor explains how these feathers confirm a longheld hypothesis that Archaeopteryx was capable of powered flight.

CNN · ‘Important moment in evolution’: Fossil preserves never-before-seen flight feathers in ‘first bird’Scientists were finally given access to a remarkable Archaeopteryx fossil that’s allowed them to better understand exactly how the earliest known bird could fly.

This week for #Fossilfriday we have another #Guess that #Lego #Fossil.

This one I would rate as medium. This Miocene-aged marine mammal is known from fossils around the world.

Reminder: hide your answer behind a content warning. This will allow others to guess without a hint. I will post the answer tomorrow (and to anyone who guesses correctly).

All these #git based solutions seem cool, but... did you tried #Fossil?

https://fossil-scm.org/home/doc/trunk/www/index.wiki

I'm using it for my pet project and compared to any of these alternatives it's simpler to host (even as a CGI on a cheap shared hosting) and more powerful as a forge.

It's different from git and you can't leverage its widespread knowhow, but definitely easier to use and operate after a pretty short learning process.

Out comes my reconstruction of a 'living' #belemnite replica to tackle a frequently asked #FossilFriday question. " What exactly are these pointy shaped fossils ". So, with my replica and a pointy shaped #fossil to hand from my collection. Reading out and rehearsing from the brilliant Discovering #Geology section of the British Geological Survey website. I open up those curious minds 😁

This one I would rate as medium. This dinosaur from Utah is from the early Cretaceous.

This one I would rate as easy. This large representative of its family is commonly thought to be the origins of a dinosaur in Jurassic Park, even though that's impossible.
