User:Geekgecko/Matt Formation
The Matt Formation, also known as the Glarner Schiefer (Glarus Slate), is an Early Oligocene-aged marine geological formation that outcrops in the Glarus Alps of the Canton of Glarus, Switzerland.[1][2] It is most notable for its fossiliferous slates found near Engi, known as the Engi slates or Glarner Fischschiefer ("Glarus fish slate"), which contain the well-preserved fossils of fishes, birds, and marine reptiles. The metamorphization of the rock has led to many of the fish fossils appearing somewhat distorted.[1]
The fossil fishes of Glarus were among the earliest known to Western science. Although the slates from Engi mines have been mined since the mid-16th century, the first description of its fossil fishes was by Johann Jakob Scheuchzer in 1705. Scheuchzer's writings prompted a flourishing trade in the fossil fishes of Glarus, which had been sent to museums all around Europe throughout the 18th century.[3] Many of these fishes were described with Linnean taxonomy for the first time in the early 19th century by Europe's pioneering paleontologists, including Henri Marie Ducrotay de Blainville and Louis Agassiz.[4][5]
Paleobiota
[edit]The Glarus slate is consistent with an open tropical marine environment that was deposited at great depths in the western Paratethys Sea. The Alpine orogeny uplifted these former deep-sea fossils far above sea level, where they are exposed today.
