To find such an advanced predatory mammal came as a surprise to these researchers. The evolutionists had long maintained that the only mammals alive at the time of the dinosaurs were very small, like the supposed human ancestor that resembled a squirrel!”Hu, Y. et al., “Large Mesozoic Mammals Fed on Young Dinosaurs,” Nature: 433, 2005, pp. 149-152.
