Miosynechodus is a dubious genus of extinct ray from the Miocene of Sri Lanka. It was originally identified as a fin spine from a late-surviving hybodontid,[1] but it is now considered to be a myliobatiform tail stinger.[2] A single species is known, Miosynechodus mora, which was named in 1969.[1]

Description

The holotype of Miosynechodus is a single tail stinger from Deraniyagala's personal collection. It measures 41 mm (1.6 in) in overall length, with a width of 10 mm (0.39 in) and a depth of 6 mm (0.24 in), and has five longitudinal grooves.[3]
