Austin Formation
The Austin Chalk is an upper Cretaceous geologic formation in the Gulf Coast region of the United States. It is named after type section outcrops near Austin, Texas. The formation is made up of chalk and marl. Fossils The putative galloanseran bird ''Austinornis lentus'' has been found in the Austin Chalk.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. The general absence of dinosaurs is a reflection of the Austin limestone being marine in origin, primarily composed of microscopic shell fragments from floating sea organisms known as "coccolithophores" (the same organisms that contributed to the White Cliffs of Dover, on the south coast of England). Nevertheless, the Austin Chalk will occasionally produce fossils of larger creatures, such as ''Inoceramus'' clams, ammonite cephalopods, and large marine vertebrates such as ''Xiphactinus'', a predaceous fish. Geology The rocks of the Austin Chalk consist of recrystallized, fossiliferous, interbedded chalks and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...
