Echinodon

(ECK-ih-no-don)(Early Cretaceous)

Inspired by Pigeon colors and patterns.

This piece is part of a project that fell through, the "ABC of Dinosaurs", where I illustrated a selection of extinct animals, some famous, others less well known in fanciful depictions. I do not claim full realism, only giving my take on one of my greatest passions in life.

Please enjoy.

A History of What Dinosaurs Were Known up until the Bone Wars

Dinosauria was first coined in 1842, only three genera were known: Iguanodon, Megalosaurus, and Hylaeosaurus (which was named that year. The Crystal Palace Park was opened in 1852 and showed the whole world what people though dinosaurs looked like at that time.

However, by then, a few dinosaurs had been added to the list and described as dinosaurs. However, most of them were teeth or otherwise remain dubious species/known from little remains.

To be fair, the initial specimens of the original three weren't that great either. Still, it was enough to get an idea of these animals.

Most histories of Dinosaur Discovery then jump to Hadrosaurus foulki which was described formally in 1858, it was published in a monogram that was meant to be released in 1860, but the civil was got in the way of that, delaying publication until 1865. This had illustrations of the animal, with a reconstruction of the skeleton being put out by 1868.

However, between 1852 and 1861, several animals were described that were realized to be dinosaurs as well. Most of them didn't change the game or were realized to be what we know them to be today.

Thecodontosaurus was the 5th overall dinosaur named and recognized as such, the 4th being a fragment they gave a name so we're not counting it. Even then, the material was not great for Thecodontosaurus, so its actual ties remained unrealized (still, they recognized it was closer to Megalosaurus than Iguanodon). Next was Cetiosaurus. Found in 1841 and thought to be a massive oceanic crocodile, it was in 1856 when it was realized to be a dinosaur, but the remains were so fragmentary as to not give away its identity as a Sauropod, shoving it in closer to Iguanodon in the Victorian's minds. Next was Scelidosaurus, like Cetiosaurus, it was described by Richard Owen in 1861. It was properly lumped in relations-wise with Hylaeosaurus, but is notable for being smaller/older than Hylaeosaurus. And it confirmed to them that those two at least were still quadrupeds.

Then in 1861 came a 1-2 punch of discoveries. Compsognathus and Archaeopteryx. That was a shakeup on a lot of levels. In top of the wider knowledge of Hadrosaurus, it really shook up the understanding of Dinosaurs known at the time.

The Kangaroo posture was all in, now. Compsognathus allowing that stance to be applied to Megalosaurus.

With that established, a few more animals of note were added to the list. Of note are the Island Dwarfs Echinodon, Struthiosaurus, and Rhabdodon. Beyond them, they added Polacanthus, Dryptosaurus (known as Laelaps at the time), Hypsolophodon, and Dacentrurus (known as Omosaurus).

Of special note is Plateosaurus. First described in 1834 and described in 1837, it wasn't recognized as a dinosaur until 1867 (as near as I can tell) primarily due to the language barrier. Since it was found in Germany and most dinosaur sciences was being done in English-speaking countries.

More fragmentary material was being found by the 1870s from the west that today is considered dubious, but 1877 was the 'start' of the Bone Wars. Why?

In that year, the following animals were discovered:

Allosaurus, Apatosaurus, Camarasaurus, Nanosaurus, and Stegosaurus. Followed shortly by Diplodocus, Brontosaurus, Camptosaurus, and Coelurus. In short, the Morrison Formation had been found. These with full skeletons, showing the diversity of the Sauropods. 1876 also gave us the first 'frill' of a ceratopsian, dubbed Monoclonious. It wasn't until 11 years later that Triceratops solidified what they looked like in the eyes of scientists.

Still, I wanted to highlight that strange time between 1852 and 1877 when there were basically three 'types' of Dinosaur: Therapods, Thyreophorans, and Ornithopods.

Dinovember day 9: Echinodon Three Echinodon shelter in a small cave as a rainstorm pours down from the heavens.

Echinodon is a species from southern UK... It was probably just as rainy then as it is now.

Note: There is ONE Heterodontosaur that we didn’t put in Pride colors because we hadn’t had the idea to do so for the HeteroDONTosaurs yet. This Heterodontosaur is Echinodon.

Feel free to fill this void

Echinodon becklesii

PLEASE support us on Patreon! This takes a lot of our time and we get no money for it from other sources, so if you would like this content to continue, please consider supporting us on Patreon!

Name: Echinodon becklesii

Name Meaning: Hedgehog Tooth

First Described: 1861

Described By: Owen

Classification: Dinosauria, Ornithischia, Heterodontosauridae

Echinodon is our first Heterodontosaurid, and it’s weird in that it is from the Early Cretaceous, where most members of this group date to the Early Jurassic. It was found in the Purbeck Beds near Swanage, England. It was a bipedal herbivore, around 60 centimeters long, and it was mistaken for a lizard by the original describer, Richard Owen himself (why did dinosaurs have to be named by such a bad scientist?) It lived in the Berriasian age of the Early Cretaceous, about 140 million years ago, and though it’s classification in the Heterodontosauridae has been controversial at times, multiple bodies of evidence have recovered it in this group.
