Dendrerpeton acadianum

Amphibia - Temnospondyli - Dendrerpetidae

Taxonomy

Dendrerpeton acadianum was named by Owen (1853). Its type specimen is BMNH R4158 (lectotype, designated by Carroll, 1967), a partial skull (partial dermal roof and fragments of palate), and it is a 3D body fossil. Its type locality is Coal Mine Point; Divison 4, Section XV, coal-group 15, which is in a Westphalian A mire/swamp sandstone/coal in the Joggins Formation of Canada. It is the type species of Dendrerpeton.

Synonyms

Hylonomus aciedentatus was named by Dawson (1860). Its type specimen is RM 2.1125, a partial skeleton (lower jaw, impression of the ventral surface of the posterior margin of the skull roof, parasphenoid, ilium, cleithrum, and vertebrae), and it is a 3D body fossil. Its type locality is Coal Mine Point; Divison 4, Section XV, coal-group 15, which is in a Westphalian A mire/swamp sandstone/coal in the Joggins Formation of Canada. It is the type species of Smilerpeton.

It was recombined as Smilerpeton aciedentatum by Hay (1902); it was synonymized subjectively with Dendrerpeton acadianum by Schoch and Milner (2014).
Dendrerpeton oweni was named by Dawson (1863). Its type specimen is RM 2.1121, a partial skeleton (skull table, maxilla, ilia, scales, vertebrae, and limb bones), and it is a 3D body fossil. Its type locality is Coal Mine Point; Divison 4, Section XV, coal-group 15, which is in a Westphalian A mire/swamp sandstone/coal in the Joggins Formation of Canada.

It was synonymized subjectively with Dendrerpeton acadianum by Steen (1934), Carroll (1967).
