Did a lack of sex hold back the evolution of the first animals? To answer this question, you need some lovely Ediacaran fossils and lots of interesting maths. An x-rated double hitter for @thefossilfiles.bsky.social this week with @egmitchell.bsky.social and @tweetisaurus.bsky.social

We also found evidence of bony skeletal type tissues in these otherwise squishy vertebrates. nice.

The specific chemistry and distribution shows evidence of a complex eye and a retinal pigmented epithelium, early in our evolution. COOL.

Robert Sansom @fossilrob.bsky.social · 28/01/2026
Let's look closer at the eye. The Copper shows a really nice Camera-type eye structure, not seen before with normal light.

Robert Sansom @fossilrob.bsky.social · 28/01/2026
The Zinc picks out nicely the eyes, the 'gills', and some mystery unknown structures, but NOT the 'mouth'

🪨💥🌎🦖🦕 What were dinosaurs up to before the asteroid hit? In the latest @thefossilfiles.bsky.social, @tweetisaurus.bsky.social and I sit down with @stevebrusatte.bsky.social to talk about new insights from New Mexico, out now on YouTube or where ever you get your podcasts youtu.be/l4Q6ifORvVY?...

Will AI replace palaeontologists? Can we use AI to find, classify, and interpret fossils? 🤖🦖🐚 New episode of @thefossilfiles.bsky.social looks at just that for #FossilFriday

Here’s a sneak peak where I feebly try to justify the 18 year gap between the genesis and completion of this project with @Emma. Can you beat this gap?

I’d prefer not to be making the final finessing touches to tomorrows talk whilst on the train to Birmingham for #SVP2025, but that is where we are

The story of Oculudentavis is wild. It was named "eye-teeth-bird" but had neither the eyes nor teeth of a bird, and indeed it wasn't even a bird. And the fossil may have come from a war zone 1/2
