I’ve always been fascinated by the animals from the era of megafauna, specifically the Pleistocene. Wikipedia is a great start, but details like paintings, behavior, etc are a bit more scarce.

Does anyone have any recommendations for good resources that are approachable for non-scientists?

Some megafauna examples:

Megaloceros, the giant deer who had antlers 12 feet wide- https://en.m.wikipedia.org/wiki/Irish_elk

Arctotherium, the largest bear and potentially the largest land carnivore, ever - https://en.m.wikipedia.org/wiki/Arctotherium

Titanis, one of the largest carnivorous terror birds - https://en.m.wikipedia.org/wiki/Titanis

Megatherium, the giant, elephant sized sloth that dug gigantic burrows - https://en.m.wikipedia.org/wiki/Megatherium

Thylacoleo carnifex, the marsupial lion, and largest carnivorous marsupial in Australia - https://en.m.wikipedia.org/wiki/Marsupial_lion

Camelops, a family of camels native to North America - https://en.m.wikipedia.org/wiki/Camelops

Thylacosmilus, a Metatherian (similar to marsupial), Sabre toothed carnivore from South America - https://en.m.wikipedia.org/wiki/Thylacosmilus
