Extinct species of synapsid "Haptodus" garnettensis Early Permian, ~304 Haptodus garnettensis.jpg Restoration of "H". garnettensis "Haptodus" garnettensis 2 Currie, 1977 "Haptodus" garnettensis is an extinct species of basal sphenacodont from the Late Carboniferous (Pennsylvanian) of Kansas, USA. Taxonomy The holotype of "Haptodus" garnettensis is RM 14156, a partially articulated skeleton (cranial and postcranial) of immature individual. More than 16 well-preserved specimen of various ontogenetic stages were referred to this species. All specimens came from the Garnett Quarry, located in the Anderson County of Kansas. They were collected from the Rock Lake Member of the Stanton Formation (Lansing Group), dating to the late Kasimovian stage of the late Pennsylvanian series, about 304 million years old.Michel Laurin 1993 Anatomy and relationships of Haptodus garnettensis, a Pennsylvanian synapsid from Kansas https://mnhn.academia.edu/MichelLaurin/Papers/1242210/Anatomy_and_relationships_of_Haptodus_garnettensis_a_Pennsylvanian_synapsid_from_Kansas Journal of Vertebrate Paleontology 13 2 200–229 10.1080/02724634.1993.10011501 Laurin (1993, 1994) suggested that Haptodus garnettensis would have to be renamed because he saw Haptodus baylei as a possible nomen dubium.Michel Laurin 1994 Re-evaluation of Cutleria wilmarthi, an Early Permian synapsid from Colorado https://mnhn.academia.edu/MichelLaurin/Papers/1242256/Re-evaluation_of_Cutleria_wilmarthi_an_Early_Permian_synapsid_from_Colorado Journal of Vertebrate Paleontology 14 1 134–138 10.1080/02724634.1994.10011544 In his dissertation revising taxa assigned to Haptodus, Spindler (2015) proposed that "Haptodus" garnettensis is not congeneric with the Haptodus type species, giving it the nomen ex dissertationae Eohaptodus. He also concluded that two specimens referred to garnettensis, ROM 43608 and ROM 43601, represent new genera and species, the former specimen being named Kenomagnathus by Spindler (2020) and latter specimen being given the nomen ex dissertationae Tenuacaptor reiszi.Spindler, F. 2015.
