Ianthasaurus is an extinct genus of small edaphosaurids from the Late Carboniferous.
It is one of the smallest edaphosaurids known, with an 8 cm (3.1 in) skull and a total body length of 75 cm (30 in). [1] Ianthasaurus lacks many of the spectacular specializations seen in Edaphosaurus . For example, the marginal dentition of Ianthasaurus is similar to that of insectivorous reptiles, with slender conical teeth which are slightly recurved at the tips, and there is a slight development of a caniniform region. The palatal and mandibular dentition is unspecialized, and there are no batteries of teeth for crushing of plant materials. Also unlike Edaphosaurus , Ianthasaurus was lightly built and was probably quite agile. The skull was similar to that of Haptodus , a sphenacodontid, though they were distantly related.
It was named by Robert R. Reisz and David Berman in 1986. [2] [3] It was discovered by them in the Upper Pennsylvanian Rock Lake Shale near Garnett, Kansas. [2]
