Haolong dongi

Haolong is a recently discovered hadrosauroid dinosaur from early Cretaceous China. This dinosaur preserves a quill-like structure not seen in other related dinosaurs. These quills aren't analogous to theropod proto-feathers or squamate spines making them unique in their own regard. The purpose of these quills is unclear but either a defensive + display structure is plausible.

Since the specimen is of a juvenile, it is unknown whether adult Haolong continued to carry the quills.

have you guys heard about the greenland shark. some crazy shit happening there.

[venndaai]

they are sexually mature at ONE HUNDRED AND FIFTY YEARS OLD.

their (live!) young gestate for. wait for it. eight to eighteen (??) YEARS. can have up to 10 at a time. good grief.

longest lifespan of any vertebrate, up to five hundred years

toxic flesh

has giant eyes but is usually blind because of a weird little crustacean that's evolved to live on and eat their eyes. this doesn't seem to bother them much.

lives in deep cold water and has the lowest swim speed and tail-beat frequency for its size across all fish species. just generally lives life in extreme slow motion

largest genome of any shark

eats everything including moose and polar bears

ma'am you are delightfully strange and I'm privileged to share a planet with you

this post prompted me to refresh my memory on Greenland Shark Facts and this detail about how they feed goes so hard

just vacuuming up their unsuspecting prey. whole !

Good news good news good news! Recent research suggests the eye parasites do NOT blind them!

Eye-opening research: Greenland sharks maintain vision for centuries through DNA repair mechanism

There is something about a giant aquatic crocodile-snouted dinosaur with a sail down its back wearing the trans pride flag that just feels right. The real Spinosaurus (~99 million years ago, North Africa) is the only non-avian dinosaur we know that swam for a living. @webvein drew this one. It’s on apparel at 252MYA.COM/STRANS.
