Cretaceous Quotes

When the dinosaurs fell at the end of the Cretaceous, they were not a senile, moribund group that had played out its evolutionary options. Rather they were vigorous, still diversifying into new or­ders and producing a variety of big­brained carnivores with the highest grade of intelligence yet present on land. (Robert T. Bakker)
One might expect that mammals would have taken over the land verte­brate communities immediately, but they did not. From their appearance in the Triassic until the end of the Creta­ceous, a span of 140 million years, mam­mals remained smal and inconspicuous while all the ecological roles of large ter­restrial herbivores and carnivores were monopolized by dinosaurs; mammals did not begin to radiate and produce large species until after the dinosaurs had al­ready become extinct at the end of the Cretaceous. One is forced to conclude that dinosaurs were competitively su­perior to mammals as large land vertebrates. And that would be baffling if dinosaurs were "cold-blooded." View quote

During the Cretaceous Period many of the inland seas dried up, leaving the Plesiosaurs stranded without any fish. Just about that time Mother Nature scrapped the whole Age of Reptiles and called for a new deal. And you can see what she got. [Footnote: Here we see the working of another Law of Nature: No water, no fish. ]. View quote
