Tinodon

Tinodon is an extinct genus of mammal alive 155–140.2 million years ago (Oxfordian-Berriasian) which has been found in the Morrison Formation (United States),[2] the Alcobaça Formation (Portugal) and the Lulworth Formation (England). It is of uncertain affinities, being most recently recovered as closer to therians than eutriconodonts but less so than allotherians.[3] Two species are known: T. bellus (Marsh, 1879) and T. micron (Ensom & Sigogneau-Russell, 2000[1]).
