Did a prehistoric mammal evolve venom millions of years before snakes?
In short: This video investigates the history of venomous mammals, focusing on the extinct Euchambersia. It explores the possibility that this creature developed venom long before the first snakes or lizards, offering a look at evolutionary timelines for toxic traits.
Euchambersia may have possessed venom approximately 20 million years before the earliest lizards and more than 150 million years before snakes appeared. The video examines the 'venomous therocephalian' hypothesis, detailing how various scientific portrayals have shaped our understanding of this ancient relative.
By collaborating with Bizarre Beasts, the presentation explores the broader context of venomous mammals, both living and extinct, to understand how these biological defenses emerged in the fossil record.
