Taeniodonts Evolution quickly into highly specialized digging , and varied greatly in size, from rat-sized to species as large as a bear. Later species developed prominent front tooth and huge for digging and rooting. Some genera, like Stylinodon, had ever-growing teeth. The scarcity of taeniodont 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 Placentalia mammal.Sarah L. Shelley (2022.) "The phylogeny of Paleocene mammals and the evolution of Placentalia", in "The Society of Vertebrate Paleontology 82nd annual meeting" Genera Alveugena, Ambilestes and Procerberus are the immediate outgroups to Taeniodonta, with genus Alveugena classified as a sister taxon to this order.
