Origins in North America
Ancestral Roots: Horses originated in North America around 55 million years ago with small, multi-toed creatures like Eohippus (also known as Hyracotherium). Imagine a creature no bigger than a beagle, navigating the lush forests of ancient North America.

The Hyracotherium (Eohippus) on the Paleocam! I took inspiration from today's Equus and their primitive markings to create the Eohippus' coat.

Reminds me of Gould's account of Hyracotherium being "the size of a fox terrier."

EOHIPPUS MY BELOVED!!!!!!!!!!!!! i based Kal's feets on eohippus. :)

He has an extra toe, but my thought was: what if this fae creature evolved similarly to horses, but since they stay often in the water, their feet haven't become the single hoof horses have?
Illustration titled "dawn horse (Hyracotherium)". It shows the animal, a brown, horselike creature with a sloped back and spots. Its legs resemble a horse or deer's leg, but its feet have toes rather than one hoof. "The Classic Horse Series" - "55 mill Eocene, Hyracotherium (Eohippus)", "35 mill Oligocene, Miohippus", "17 mill Miocene, Merychippus", "Today, Equus (Horse)". Below each label is a bone diagram of a foot. Eohippus has four toes, Miohippus has three with a large central toe, Merychippus has three but the two side toes are small, and Equus has only one. Reference illustration labeled Kal Douglass - kelpie form. He is a teal-green, lithe horse-like creature covered in darker green plant-like hairs which also make his mane and tail. The center of his tail and two antennae from his head are a thin dark blue tendril with a light green bulb on the end. His underside is scaly and lighter green, and he has light green gills along his body, as well as light green frills or fins on his legs. His legs end in a five-toed foot with webbing that, when held closed, resembles a horse hoof. His eyes are dark with a sliver of green light inside, and his mouth while covered in skin resembles a horse skull. His teeth are sharp, and his tongue is green. His pose is that of a swimming horse, and some small illustrations nearby provide a view of his mouth open to show his teeth and tongue, and his foot both in its held-together hooflike state and when the fingers are flexed to become a webbed fin for swimming. Illustration of Kal in kelpie form. He is a teal-green, lithe horse-like creature covered in darker green plant-like hairs which also make his mane and tail. The center of his tail and two antennae from his head are a thin dark blue tendril with a light green bulb on the end, each emitting light. His underside is scaly and lighter green, and he has light green gills along his body, as well as light green frills or fins on his legs.

A couple of weeks ago I had a dream that I was living in a big ol’ rambling sharehouse on a large block with a particular friend of mine. Together the house collectively adopted two prehistoric horses (Hyracotherium) but they were missing, like, half their snouts/noses “because they had a hard life”

Maybe I should actually try posting stuff instead of just lurking here, so why not have some paleo art c:

Digital drawing of a Hyracotherium, the first member of the horse family, also called dawn horse. The creature is depicted as happily rearing unicorn in dawn colors, with the writing 'dawn horse' next to it.

For today's #MakeAPlanet quiz, rank these fossil sizes from smallest to largest:

1) Wingspan of Meganeura, a Carboniferous dragonfly

2) Shoulder height of Hyracotherium, the first horse

3) Beak-to-tail length of Archaeopteryx

4) Length of a ("Giant Claw") Therizinosaurus claw

A similar genre that fascinates me is the unhelpfully bespoke metaphor as absurd contagion, cf. Gould’s case of the fox terrier as size reference for the Hyracotherium, which persisted despite the breed’s relative obscurity.

Similar to Stephen Jay Gould's "Case of the Creeping Fox Terrier Clone," where Eohippus/Hyracotherium was claimed to be the "size of a fox terrier", repeated over countless publications without checking the size/weight of a fox terrier (less than 1/2 the weight of Hyracotherium).

If there was an eohippus/hyracotherium/ prehistoric horse toy would it go in the prehistoric animals or horse collection..? Much to consider

Clyde: The dawn horse, Hyracotherium, shows evidence of dwarfing both at the PETM and a later hypothermal (warming) event.

The OG version was I believe hyracotherium and it was indeed yassified to become the horses we know today!

(Through evolution and whatnot, but listen, Darwin wrote a whole book on how finches served ✨✨FUNCTION✨✨, we can describe evolution as yassification sometimes)

Brian Jacques is unstuck in time.
Hyracotherium, a relative (but probably not ancestor) of the line leading to modern equids (horses, donkeys, zebras, etc.). It lived around 50 million years ago. The illustration shows it with hypothetical horizontal stripes on a tan coat (to aid with camouflage in its forest habitat). It's about the same size as an outline of a modern domestic cat. Diagrams of its foot bones show four toes on the front feet and three on the rear; both have a prominent central toe that foreshadows the evolution of the modern hoof.

A recent study showed that horses appeared later (50 Mya) than what we previously thought (56 Mya) 🐎
Indeed, Hyracotherium (aka Eohippus - dawn horse) and Pliolophus are not horses nor even hippomorphs in this lattest phylogeny 🤯
