weirdest: the eocene fossil lizard Saniwa, which had two parietal eyes; both a pineal eye and a parapineal eye, or at least had both of the appropriate holes in the top of the skull, like the few jawless fish that are the only living animals to have both a pineal eye and parapineal eye. The only known jawed vertebrate to have this condition.

(probably linked in the wikipedia article you linked about the parietal eye, but here's a direct link)

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.

Hosting this podcast episode was so much fun! Dr. Sarah Gabbott described her discovery of a remarkably preserved 444-million-year-old fossil that puzzled her for 25 years, her prior work on ancient hagfish that overturned the prevailing theory for the evolution of the eye, her path to becoming a paleontologist, her new book on technofossils, her favorite hobbies outside of work, and more!

Being an archaeologist, I'm always confused when palaeontologists talk about all animal remains as "fossils". I use that word strictly for things that are stuck in sedimentary rock, where often no original substance remains. A mammoth bone found in gravel is not a fossil. It's a bone.

You'll occasionally hear them saying "sub-fossil". It means "not a fossil, still an actual bone".

When insect fossils are this intact, just looking at them makes you go WHOA. Plus, preserved body structures reveal how their group evolved!

In my latest for CNN, I wrote about how a truly stunning cicada fossil from Germany's Messel Pit places singing cicadas in Europe earlier than expected, by millions of years. Its large abdomen hints that males had a roomy resonating chamber, for producing louder songs.

CNN · Newly named ancient cicada fossil is so well preserved you can see the veins in its wingsTwo fossils of singing cicadas, one of which was remarkably well preserved, reveals that the insects dispersed in Europe millions of years earlier than once thought.
