American Megafauna is a board game on the topic of evolution designed by Phil Eklund, and published by Sierra Madre Games in 1997. The game begins after the Permian-Triassic extinction event of 250 million years ago, which killed off 95% of all living species on Earth.

What were megafauna and what happened to them?

Between 50,000 and 10,000 years ago, during the final millennia of the Pleistocene Epoch, roughly 100 genera of megafauna (animals weighing more than 100 pounds) became extinct worldwide. Martin reviews the end-Pleistocene extinction, arguing that overkill is the more likely explanation.

What killed megafauna?

Research suggests extreme climates, not humans, wiped them out. Human activities and population growth have wrought much destruction to life on Earth. But when it comes to megafauna extinctions, evidence suggests we may be off the hook – rather, the major culprit could be climate change.

Is a deer a megafauna?

Are there any megafauna left in the world?

In conclusion, anthropogenic pressures on megafauna since the Late Pleistocene have resulted in dramatic losses, especially in the megaherbivores and megacarnivores, of which only 9 and 6 species respectively remain worldwide of the 50 and 15 that existed in the Late Pleistocene.

Are there any megafauna in the Beringia region?
