Indohyaenodon (meaning "Indian hyena tooth") is an extinct genus of hyaenodont that lived from Early to Late Eocene in Cambay Shale Formation of Gujarat, India. It is from the family Indohyaenodontidae and is the sister taxa of Yarshea cruenta. The type and the only known species is Indohyaenodon raoi.[2][3]
Description[]
Indohyaenodon was a relatively small to medium-sized hyaenodont, smaller than Hyaenodon gigas, who was about the size of the a Lion. It is the only known hyaenodont from its region and might have also been the apex predator of Cambay Shale Formation. It can be distinguished from other hyaenodonts on the basis of its molar tooths, as they're narrow in shape and increases in size from hinder part to fore part of the dentary.
Discovery and Naming[]
Fossils of Indohyaenodon were discovered in Vastan mines of Cambay Shale Formation, alongside other faunal fossils. In 2009, Bajpai and his colleagues named it as a new genus and species of hyaenodont, Indohyaenodon raoi, where the genus name "Indo" is after the country of India, "Hyaeo" is the genus name for striped hyena(Hyaena Hyaena), "don" is the greek word for tooth and the species name "raoi" after A. Ranga Rao, who helped and contributed in research of Eocene mammals of Gujarat.
Classification[]
Indohyaenodon was originally classified as a member on hyaenodontid family, under proviverrinae subfamily. In 2013, it was classified as its own unique subfamily under hyaenodontids called indohyaenodoninae with Paratritemnodon and Kyawdawia. Later the subfamily became a new family with the addition of Yarshea, distinct from hyaenodontids.
