No clear evolutionary path in the fossil record.
…for the creatures that have no bones and only a beak that could even fossilize? Color me SHOCKED their ancestors didn’t leave fossils.

You… are looking at a fossil of one. That’s what the post is about. I mean, maybe they fossilize less frequent than other animals, but it seems like they do.

Yup. It’s not that soft tissue DOESN’T fossilize, it’s just that the conditions to do so are much rather, and soft tissue is obviously much more susceptible to degradation before fossilization.

Not gonna lie, I was assuming even the picture was made up/AI bullshit. Bit of egg on my face there

The sentiment is still correct though, even bone fossils are exceedingly rare. I can’t remember the exact estimate but of all the people alive in the US, archeologists 1 million years from now would be lucky to find 60 human bones. I’m not sure if that included teeth however.
