To which is added an appendix, containing a tabular view of the Tertiary fossils hitherto discovered in North America.. [Samuel George Morton]. Although they weren't technically dinosaurs, the marine reptiles known as mosasaurs hold a unique place in paleontological history: it was the discovery of a specimen of Mosasaurus in , in a Dutch quarry, that galvanized scientists into the realization that species could become extinct (and that the earth used to be populated by some very strange creatures .

Although the best-known Cretaceous animals were the dinosaurs, they weren’t the only animals around at the time. Scurrying between the feet of fearsome meat eaters such as Tyrannosaurus and Spinosaurus were many types of early mammal – some of which (as you’ll find out below) were even big enough to eat small.
The Cretaceous (/ k r ɪ ˈ t eɪ. ʃ ə s /, krih-TAY-shəs) is a geological period that lasted from about to 66 million years ago (mya). It is the third and final period of the Mesozoic Era, as well as the name is derived from the Latin creta, 'chalk'. It is usually abbreviated K, for its German translation Kreide.
The Cretaceous was a period with a relatively warm climate. Sierra Club Books (San Francisco): pp. Leidy, J., Cretaceous Reptiles of the United States. Smithsonian Contributions to Knowledge 1.

He has also served as a special advisor for programs and motion pictures about dinosaurs in the United States, Great Britain and Japan. AFTER an interval of nearly ten years, Dr. Hayden presents us with further contributions, by Lesquereux, to the Cretaceous and Tertiary floras of the United States.
Extinction of these large reptiles left many ecological niches open and available. Small mammals that survived the Cretaceous extinction event were able to flourish by filling these niches.
Mammals also were warm-blooded and better able to adapt to a wider range of environments. Pages in category "Cretaceous reptiles" The following 4 pages are in this category, out of 4 total. This list may not reflect recent changes ().
This chapter discusses the marine reptiles and Mesozoic biochronology. Marine reptiles of the Mesozoic were the Placodontia, Nothosauria, Mosasauria, Thallatosauria, Ichthyosauria, Plesiosauria, and Hupehsuchia. Ichthyosaurs appeared during the Early Triassic and persisted until the beginning of the Late Cretaceous.
Late Cretaceous dinosaurs from southeastern states are a significant subset of known eastern North American dinosaurs. Most eastern North American Late Cretaceous dinosaur specimens come from the New Jersey-Delaware-Maryland coastal plain (50); others are from Alabama (21), Mississippi (10), North Carolina (10), Georgia (6), Missouri (1), and.
