Dinosaur of the Month: Hadrosaurid!

1  2018-11-12 by Cdace

Hadrosaurids (meaning "bulky lizards") were the family of duck-billed, herbivorous dinosaurs. They were very common dinosaurs. Hadrosaurs ranged in size from 10 to 40 feet (3 to 12 m) long. They had horny, toothless beaks and hundreds of cheek teeth in the sides of their jaws. The duck-billed dinosaurs had the most teeth; they had up to about 960 cheek teeth. Hadrosaurs had a stiff tail that was probably used for balance. They had hoof-like nails on their feet, and bumpy skin. They ran on two legs, holding their tail and head in a horizontal position. They may have walked on all four legs while grazing. Hadrosaurs probably lived near bodies of water, migrating to high ground to lay eggs. It used to be thought that they had webbed hands, but this was an artifact of the fossilization process.

Hadrosaurs are closely related to the Iguanodontids, and are probably their descendants. Hadrosaurs were Ornithischians (the order of bird-hipped dinosaurs) and Ornithopods ("bird-footed" herbivores with hoof-like feet). Hadrosaurs are divided into two groups, the Hadrodsaurinae (non-crested hadrosaurs) and the Lambeosaurinae (hadrosaurs that had skull crests that connected with their nasal passages).

Hadrosaurs lived during the late Cretaceous period. Their fossils have been found in North America, Europe, and Asia.

Although it has been long believed that hadrosaurs originated in Asia, the new find, Protohadros byrdi, seems to shift the birthplace of hadrosaurs to North America. Protohadros byrdi dates from 95.5 million years ago, was recently found in Texas, USA

"We don't see much expansion of brain size in this group of animals [dinosaurs] as they go through time, unlike a lot of mammalian and bird groups, where you see increases in brain size over time,"

No shit their brains aren’t growing. They are already the smartest being alive they don’t need anymore brains lmao

It is true that, in general, dinosaurs' brains were much smaller than the brains of mammals possessing heads of comparable size. Whereas in a human skull, most of what is under the immediate bone surface is brain matter, a dinosaur skull's key facet is its jaw structure; much of the available space was occupied by powerful biting muscles, with the brain being buried under a thick casing to keep it well protected.

Bruh their dinosaur brains are like a modern microprocessor compared to the mammals brain that are like giant shit processors of the 70s-80s

Now hold up. This is just mean. Take it back. Pajeets are so much worse than any real animal.

Okay. Cats>dogs>dinos>pajeets>/u/Cdace.

rude

This is /r/drama, fam.

Oh fuck I thought this was r/dinosaurs

GTFO

No you need dinosaur πŸ¦– knowledge whether you want it or not

cdace do u play jurassic world alive

The new park building game? Nah I was thinking about it but I bought red dead 2 instead. Honestly though I haven’t had time to play much recently I’m busy getting my associates of science for civil and mechanical engineering this semester and setting up my transfer to get a bachelors

no lol i meant the dinosaur version of pokemon go

also shame on u for wasting time on a future other than being dinosaur dinner

there must be sacrifices pending return of blessed overlords and consumption of the human race

Sacrifices of time and money to do what is necessary and beautiful

Imagine trying to build a device to bring back the dinosaurs πŸ¦– from the plasma fold without an understanding of engineering smh

Why is the cow of the dinosaur world the dinosaur of the month

posts like this make me think that it would be fine to post the korean dinosaur song and propose that it be ordained as /r/drama's theme song

but I'm afraid of being ridiculed by my /r/drama peers and banned by the mods.

If this is what you’re talking about then absolutely

yep, that's it.
