#FossilFriday Skull of Homalodotherium, a ~18 million-year-old, bear-sized#notoungulate from Patagonia.
Check out the "remarkable and gradual transition from the first incisor to the last molar" noted by Flower (1874). For this reason, it was named "even tooth beast." #teethpic.twitter.com/AyQ1fT0qiD

#FossilFriday Pristine "roadkill" specimen of the late#Oligocene (~25 Ma)#notoungulate Scarrittia canquelensis from@AMNH. Incredibly, this isn't the holotype, which is "a specimen not collected and now unidentifiable" that its namer, G.G. Simpson, left in#Argentina!pic.twitter.com/gE9dJLnEyT

#FossilFriday follow-up on@Synapsida's fantastic Adinotherium skull: photos of the palate and complex, high-crowned#teeth of this#Miocene#notoungulate, which became less complex with wear. It is one of the few native S. American ungulates that may have had a rhino-like horn! pic.twitter.com/ULwIM3d4un

#FossilFriday Is this a#rodent skull?
Nope! It is Mesotherium, a sheep-sized #notoungulate (South American native "ungulate") on display@naturales_unlp.
Its ever-growing upper incisors are rodent-like, but its lower incisors are more like those of #wombats.#teethpic.twitter.com/zYFgeUqf3C

#FossilFriday What is your#Specimen2020?
This is UATF-V-002020: a ~15 million-year-old #notoungulate jaw from#Bolivia with one small#tooth. The thick later of cement on the outside (also found in#horses) strengthened and supported this herbivore's ever-growing molars.pic.twitter.com/bUaVPyDEWu

#FossilFriday
Skull of the large #Miocene#notoungulate Trigodon from#Argentina. Its main claim to fame is that it may have had a#rhino-like horn
. However, it also had five lower incisors, two pairs and one in the middle - quite odd (literally)! #teeth#SANUngulatepic.twitter.com/9X99lngLqq

#FossilFriday Partial cranium of the#notoungulate Tremacyllus from the#Pliocene of#Argentina
. These
-sized mammals evolved remarkably #rodent-like jaw muscles, but the tall, pointed cusps on their ever-growing#teeth indicate that they chewed quite differently.pic.twitter.com/EzRG88eMWD

#FossilFriday "Psychedelic" and "normal" photos of a 30 million-year-old archaeohyracid#notoungulate jaw from#Chile. The tooth tissues (enamel and dentin) really pop under the UV light! Where the teeth weren't completely cleaned, the surface is black.#teeth@AMNH#Oligocenepic.twitter.com/tf77MeIl1l

#FossilFriday Curved upper molars of the#Miocene#notoungulate Pericotoxodon. The top and bottom of each tooth look the same because they grew continuously and never formed roots. Richard Owen named the family for this feature (Toxodontidae = bow tooth).#Teeth#HornedArmadillospic.twitter.com/ut6g51MU1D
