Named By: S. Glienke - 2012.
Classification: Chordata, Amphibia, Recumbirostra.
Species: A. schroederi (type).
Diet: Probably carnivore.
Size: Uncertain due to incomplete remains.
Known locations: Germany - Altenglan Formation.
Time period: Late Carboniferous/Early Permian.
Fossil representation: Partial skull with vertebrae, ribs and parts of the pectoral girdle.
holotype specimen of Altenglanerpeton was first
found during the
1870s, and initially described as a specimen of the microsaur genus
in 1939. The specimen was not renamed as a new genus
until 2012 after some debate over whether the specimen was actually
that of a microsaur.
In life Altenglanerpeton would have had a very slender body and greatly reduced limbs. This body type would have allowed Altenglanerpeton to swim by a lateral (side to side) undulation of the body while being able to navigate through weeds and submerged obstacles. The holotype specimen of Altenglanerpeton was recovered from a fossilised deposit of lake sediment, confirming that in life Altenglanerpeton probably spent much of its time in the water. Altenglanerpeton may be closely related to the genus Tambaroter.
