My favorite thing about dromaeosaurids has to be how drastically different they were compared to how they are portrayed in the media. They probably have THE most drastic difference. An accurate T. rex or sauropod still reads as “dinosaur” to the general public, but to someone who is uneducated on dinosaurs, accurate dromaeosaurids read as “weird bird” (and while birds ARE dinosaurs, the average person doesn’t know that). The only real thing that connects the two is the famous sickle claw.
It may be Utahraptor week, but the best example of this is definitely Velociraptor due to its claim to fame in Jurassic Park (which isn’t even from the Jurassic, like many other dinosaurs in the books and films).
(also excuse my messy drawing, I just wanted to throw something together quickly)
A ground breaking new book that brings together two of the major disciplines behind Jurassic Park is aiming to raise the profile of insect fossils through stunning photographs and unique illustrations.
Fossil Insects, by Dr David Penney and James E Jepson, details the incredible preservation and diversity of fossilised insects from around the world, setting the scene for what these remarkable fossils can tell us about the ancient and modern worlds, and even the future of our planet. Like the mosquito in Jurassic Park, many of the hundreds of thousands of specimens of ancient insect have been preserved in amber.
happy Friday everybody, it’s time for another installment of Weird Biology! and today, you’re going to learn about a goddamn dinosaur.
(yes, I know all birds are technically dinosaurs, but this one is… dinosaurier? dinosaurien? DINOSAURIEST than the rest)
meet the Hoatzin, relic of ages past
*raptor screech*
the Hoatzin is the only member of the family Opisthocomidae, an ancient line of birds that branched off from the rest some 64 million years ago. this would have been just shortly after the event that murdered the shit out of all non-avian dinosaurs. to death.
Hoatzins are the very last survivors of this ancient line. (I wanted to make a joke here, but that’s actually really fucking tragic)
shit I made myself sad, MORE JOKES
Hoatzins are common pheasant-sized birds that live in the riverside forests of South America, where they survive on a diet of *drumroll* leaves. yum.
seriously, they are one of exactly two known bird species to specialize in leaf-eating, having evolved past their shame trait some 30 million years ago. (the other one is the Kakapo, who mostly just seems confused)
Kakawho?
their love of delicious delicious leaves gives them a very… distinctive odor, shall we say. this is due to their fermentative digestive process. it has earned the Hoatzin the local name ‘Stinkybird”, which for any Hoatzins reading this, is really more of an affectionate nickname. honest.
but what truly sets Hoatzins apart, and proves their saurian nature, is this.
HOLY SHIT A DINOSAUR
the hatchlings have fucking claws on their wings. remind you of anything? like maybe, oh I dunno, this guy?
HOLY SHIT A BIRD
Archaeopteryx up there bears a striking resemblance to our Hoatzin friend, which did not go unnoticed by the scientific community (who was actually paying attention this time, they swear). in fact, this uncanny resemblance helped finalize the theoretical link between dinosaurs and birds, which we now know are the same fucking thing. (more or less)
but anyway, the baby Hoatzins use those scientifically-groundbreaking claws to scramble around in trees and avoid predators. also apparently the claws just kind of… fall off?.. when the bird becomes an adult. like, imagine if your fingers all fell off at puberty, how weird would that be? jesus.
(Hoatzins definitely aren’t the only birds with wing claws, but DON’T TELL THEM THAT. they like to feel special.)
thankfully, it looks like these evolutionary weirdos will be with us for some time to come, as Hoatzins continue to be plentiful in their range. we hope they and those weird dinosaur claws stick around for a long, long time.
Maybe medieval people happened upon a T-Rex fossil and came to a relatively logical conclusion that dragons existed.
I’ve read a couple books on this actually, thats exactly what happened. Also cyclops are from looking at bones from a certain type of baby elephant. The giant note hole and tiny eyes made it look like a single eye.
Yep, can confirm! And what’s even funnier to me is that back in the dark ages, Greek people used to find a lot of prehistoric bear skeletons – and those look exactly like human skeletons, except they’re like eight feet tall or something – so they naturally assumed those were the heroes of legend, and made armour and clothes for them and reburied them with the most splendid and sacred religious ceremonies they could think of? Fast forward five centuries, Athens’ all modern and rational, philosophers and scientists aren’t taking any shit from anyone – but the problem is, people will randomly find graves containing giant-ass warriors, so that’s something that can’t be explained away and yeah, demigods were a thing and yeah, they used to be eight feet tall and sorry I don’t make the rules.
Some scientists suspect that the origin of the cyclops myths came about because of elephant skulls, which are vaguely human in shape but with a honking big hole in the middle for the trunk but easily mistakable for an eye socket without any flesh
These hypotheses are heavily debated so I want to be clear when posting that this is in no way 100% fact.
…but I also want to add that the dinosaur Protoceratops or similar genera are hypothesized by folk scientist Adrienne Mayor to have been partially responsible for the griffin myth.
(via wikipedia commons)
I mean, yeah, I can sorta see how someone could mistake that for some half-bird, half-mammal beast, especially with incomplete remains that fossils almost always have as well as the lack of knowledge of what a dinosaur is.
Whether or not it’s true? Who really knows at this point, but it’s fun to think about.
Adrienne Mayor has a book out called The First Fossil Hunters on this exact topic if anyone is interested. I haven’t read it myself though so I couldn’t tell you how good or bad it is!
Part of me, reading this: those are some super cool theories, and sound fairly plausible too – and the reburied bears thing is hilarious
A much larger part of me: I see you trying to convince me that dragons never existed, and i call bullshit
