Ictitherium (meaning "weasel beast") is an extinct genus belonging to the family Hyaenidae and the subfamily Ictitheriinae erected by Trouessart in 1897.[1] Ictitherium lived throughout Eurasia during the Late Miocene.[2]
Description
[edit]Ictitherium were around 1.2 metres (4 ft) long, and looked more like civets than modern hyenas, possessing a long body with short legs and a possibly short tail.[citation needed]
Palaeoecology
[edit]It is speculated that I. viverrinum was an opportunistic feeder,[3] and that it ate plants as well as medium-small mammals and birds.[4] It would have consumed bone, as its teeth were much more suited for osteophagy than more basal hyaenids because its Hunter-Schreger bands (HSBs) were zigzag throughout the enamel with the exception of the cervix.[5] I. viverrinum occupied a similar ecological niche as and competed with Hyaenictitherium wongii.[6] Ictitherium was a very successful and abundant genus, with multiple fossils often being found at a single site.[7]
