Taeniodonta ("banded teeth") is an extinct early group of mammals known from the Palaeocene to the Eocene. Taeniodonts evolved quickly into highly specialized digging animals, and varied greatly in size, from rat-sized to species as large as a bear. Later species developed prominent front teeth and huge claws for digging and rooting. Some genera, like Stylinodon, had ever-growing teeth.[1]

Two families belong to this group, Stylinodontidae and Conoryctidae. They were endemic to North America. The scarcity of taeniodont fossils can be explained by the fact that these animals probably lived in the drier parts of the continent where fossilization was less frequent. Taeniodonts may be related to Cimolesta, but they're unambiguously non-placental eutherians.[2]
