Palæont. [f. mod.L. Tillodontia, f. Gr. τίλλ-ειν to pluck + ὀδούς, ὀδοντ- tooth.] A member of the Tillodontia, a group of extinct mammals apparently combining the characters of ungulates, rodents, and carnivora, whose remains are found in the Eocene of N. America.
[1875. Amer. Jrnl. Sci., Ser. III. IX. 221. At the last meeting of the Connecticut Academy, Feb. 17th, Professor O. C. Marsh made a communication on a new order of Eocene Mammals, for which he proposed the name Tillodontia.
1876. Marsh, ibid., XI. 249.]
1889. Nicholson & Lydekker, Palæont., II. 1408. The characters presented by the Tillodonts harmonise with the view that both the Ungulates and Rodents have been derived from a primitive Carnivorous stock.
