Ctenacanthiformes
Ctenacanthiformes is an extinct order of cartilaginous fish. They possessed ornamented fin spines at the front of their dorsal fins and cladodont-type dentition, that is typically of a grasping morphology, though some taxa developed cutting and gouging tooth morphologies. Some ctenacanths are thought to have reached sizes comparable to the great white shark, with body lengths of up to and weights of , while others reached lengths of only . The earliest ctenacanths appeared during the Frasnian stage of the Late Devonian (~383-372 million years ago), with the group reaching their greatest diversity during the Early Carboniferous ( Mississippian), and continued to exist into at least the Middle Permian (Guadalupian). Some authors have suggested members of the family Ctenacanthidae may have survived into the Cretaceous based on teeth found in deep water deposits of Valanginian age in France and Austria, however, other authors contend that the similarity of these teeth to Paleozoic ct ...

Glencartholm Volcanic Beds Formation
Glencartholm is a location in Dumfries and Galloway, southern Scotland, along the River Esk. The Glencartholm Volcanic Beds contain a Palaeozoic (specifically Carboniferous) fossil fish site of international importance. Discovered in 1879, most of the fossils were removed during the 1930s, but in the 1990s a further site east, named Mumbie, was excavated. This led to the identification of further fish beds, where over 200 specimens of ray-finned fish were collected, including one possible new species There is also a farmhouse known as Glencartholm, or Glencartholm Farmhouse, which is a listed building in the parish of Canonbie, not far from the border with England, and near Glencartholm Wood. The farm has an inscription celebrating the defeat of Napoleon at the Battle of Waterloo The Battle of Waterloo was fought on Sunday 18 June 1815, near Waterloo, Belgium, Waterloo (then in the United Kingdom of the Netherlands, now in Belgium), marking the end of the Napoleonic W ...

Prehistoric Cartilaginous Fish 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. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous Fish Of Europe
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. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon. 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.
