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.

💁🏻‍♀️ ICYMI: 🌊🦑 The Clarion Clipperton Zone holds a surprise: metal-rich nodules surrounded by unique marine life. Scientists have found over 5,000 species there, but 90% still await formal scientific names!

From "gummy squirrel" sea cucumbers to walking #squid and carnivorous sponges with tiny hooks, this #video examines the #biodiversity in an area covering half of #Earth's surface that we've barely begun to understand.
