Kuehneotherium is an early mammaliaform genus, previously considered a holothere, that lived during the Late Triassic-Early Jurassic Epochs and is characterized by reversed-triangle pattern of molar cusps.

It lived alongside another early mammaliaform, Morganucodon, which had teeth that could crush harder insects such as beetles.

This distinction in diet shows that early mammaliaforms adapted to have separate feeding niches so they would not compete for food.

[3][4] Remains of Kuehneotherium praecursoris have been found in the Pontalun Quarry in a single fissure pocket in South Wales.

[1] During the Late Triassic epoch the supercontinent Pangaea was intact, allowing easy interchange and migration of animals across the connected continents.

When the continents began to rift apart during the Jurassic, shallow seas covered the British Isles, where Kuehneotherium was first found.

Its remains were swept into limestone caves and fissures formed by the shallow seas and were preserved as fossils in clastic sediment.

Kuehneotherium’s place in Holotheria is considered unstable, as it is difficult to determine a species characteristics based upon only mandible and dental fragments.
