Cryptovenator Hirschbergeri
''Cryptovenator'' (''Crypto'', from Greek kryptos (hidden, secret); ''venator'', from Latin (hunter)) is an extinct genus of sphenacodontid "pelycosaurs" which existed in Germany during the latest Carboniferous (late Gzhelian age, 300 Ma ± 2.4 Ma). It is known from the holotype LFN−PW 2008/5599−LS, an anterior right mandible fragment, recovered from a dark, fine grained sandstone of the middle Remigiusberg Formation. It was first named by Jörg Fröbisch, Rainer R. Schoch, Johannes Müller, Thomas Schindler and Dieter Schweiss in 2011 and the type species is ''Cryptovenator hirschbergeri''.

Carboniferous
The Carboniferous ( ) is a Geologic time scale, geologic period and System (stratigraphy), system of the Paleozoic era (geology), era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon (geology), eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeohatteria Longicaudata
''Palaeohatteria'' is an extinct genus of basal sphenacodonts known from the Early Permian period (Sakmarian stage) of Saxony, Germany. It contains a single species, ''Palaeohatteria longicaudata''. Discovery ''Palaeohatteria'' is based on very young individuals including skulls and partial postcranial skeletons. All specimens were collected at Niederhäslich locality, in Dresden, from the Niederhäslich Limestone Member of the Niederhäslich Formation, Rotliegend Group (Döhlen Basin), dating to the Sakmarian stage of the Cisuralian series, about 295.0 to 290.1 million years old. Description ''Palaeohatteria'' was a fairly small synapsid, up to 60 cm in length and with a mass of about 3 kg. The affinities of ''Palaeohatteria'' to the pelycosaur were first described in details by Alfred Sherwood Romer and Llewellyn Price (1940). They revised the taxonomy of pelycosaurs and synonymized ''Palaeohatteria'' (alongside with ''Pantelosaurus'' and others) with ''Hapto ...

Prehistoric Synapsid Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded.

Carboniferous Synapsids
The Carboniferous ( ) is a geologic period and system of the Paleozoic era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma.

In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian and the later Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the period during which both terrestrial animal and land plant life was well established.
