What Happened to the Forgotten Mammals of the Mesozoic? | Documentary
In this space documentary, we step into the hidden world of the Mesozoic, where small mammals lived in the shadows of dinosaurs that dominated the Earth. Though nearly invisible in the fossil record, creatures like Morganucodon and the multituberculates reveal a story of complex teeth, advanced jaws, and remarkable adaptability. This space documentary uncovers how these early mammals survived in dense forests, active at night to avoid giant predators—only to seemingly vanish without explanation. What caused their disappearance, and what clues remain buried in ancient sediment? Join this space documentary as we uncover the forgotten mammals of the Mesozoic and the evolutionary mystery they left behind.
