Gladbachus is a possible²³ genus of extinct chondrichthyan from the Middle Devonian Lower Plattenkalk of Germany.⁴

Discovery and naming

The holotype, UMZC 2000.32, was discovered in the Lower Plattenkalk of Unterthal, Bergisch Gladbach, Germany and it consists of a partial skull which has been compressed.¹⁵ Gladbachus adentatus was named and described by Heidtke & Krätschmer (2001).¹

The holotype was redescribed by Coates et al. (2018).⁵

Description

Gladbachus has been estimated to reach around 80 centimetres (31 in) long when fully grown.⁵
