Extinct order of mammals
Taeniodonta ("banded teeth") is an
extinct
order of
eutherian
mammals , that lived in
North America and
Europe from the late
Cretaceous (
Maastrichtian ) to middle
Eocene .
[3]
[4]
[5]
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.
[6] The scarcity of taeniodont
fossils can be explained by the fact that these animals probably lived in dry or arid climates unconductive to fossilization.
According to 2022 studies of Bertrand, O. C. and Sarah L. Shelley, taeniodonts are identified to be a basal
placental mammal.
[7]
[8] Genera
Ambilestes ,
Procerberus and
Alveugena are the immediate outgroup to Taeniodonta.
