Modern turtles have a horny beak without teeth in their mouth. In contrast, Odontochelys fossils were found to have had teeth embedded in their upper and lower jaws. [4] One of the most striking features of turtles, both modern and prehistoric alike, are their dorsal shells, forming an armored carapace over the body of the animal.
Mosasaur remains were also discovered in Africa and California. [10] In 1967 Dale Russell published a scientific monograph dedicated to mosasaurs. [11] Embryonic remains in the 1990s confirmed that mosasaurs gave live birth like in ichthyosaurs. [12]

Nothing is known of this turtle's reproductive strategy, with the exception of their egg development. Desmatochelys is hypothesized to have laid rigid eggs instead of the soft-shelled eggs typical of extant marine turtles, as a closely related protostegid has been shown to do. [20] The fossils discovered in 2007 represent an almost complete ...
So Coral’s eggs were moved to a more suitable part of the beach in Mexico, according to the DNR. Kemp’s ridley turtles, first discovered in the 1880s, are the smallest sea turtles, the DNR ...
Acrocanthosaurus.. Archaeologist Jack. T. Hughes has found evidence that the paleo-Indians of Texas collected fossils. [20] After the establishment of paleontology as a formal science, in 1878, professor Jacob Boll made the first scientifically documented Texan fossil finds in Archer and Wichita counties while collecting fossils on behalf of Edward Drinker Cope.
