This #FossilFriday morphological analysis of dental & mandibular characters of #Litoptern fossils, the group of #Extinct South American ungulates, helps to unravel their timing of diversification & phylogeny!

#FossilFriday 🇦🇷💀Beautiful ~20 million-year-old #litoptern skull from #Argentina, showing the widely spaced front #teeth characteristic of the family. The genus name, Cramauchenia, is an anagram of the well-known #Pleistocene genus Macrauchenia. On display @FieldMuseum
#FossilFriday 🇧🇴Three photos of a beautiful 13 million-year-old lower jaw of the #litoptern Llullataruca shockeyi from #Bolivia: (1) as discovered (by our geologist!); (2) after extraction; and (3) after preparation, as shown in the 2018 JVP article by @mcgratherium et al.
Anisolophus was a proterotheriid #litoptern from early #Miocene #Argentina. Like other proterotheriids it had a large tusk-like incisor which in some species was sexually dimorphic suggesting that it was used in intraspecific combat! #FossilFriday (photo mine from @yalepeabody)
Which species do they represent? Australogale leptognathus (small, meat-eating #marsupial), Palaeothentes relictus (small palaeothentid marsupial), Llullataruca shockeyi (#litoptern), Megathericulus patagonicus (#sloth), and an unnamed new species of #armadillo. #SANU #Xenarthra
#FossilFriday 🇦🇷🇧🇴🇵🇪🇨🇴A taste of S. American #ungulate diversity - from the intro article to our #SANU Gondwanan Perspectives @ameghiniana issue, published yesterday! Articles by @mcgratherium, @Javier_N_Gelfo, et al. #Notoungulate #Litoptern #Astrapothere https://t.co/Nwj45pSecq
#FossilFriday Are these #teeth from an extinct #hominin? Nope! They are from Megadolodus, a #Miocene #litoptern from #Colombia 🇨🇴that probably fed on hard fruits rather than soft leaves like most litopterns. @ucmpberkeley #SANU
#FossilFriday Palate of the #Pleistocene #litoptern Macraucheniopsis on display @museodelaplata, showing the round fossettes that develop on macraucheniid teeth with wear. See also this recent article on tooth eruption and wear in Xenorhinotherium https://t.co/Mi04CJ6McN
#FossilFriday Trio of #Miocene endemic S. American ungulates from Lonquimay, Chile: #notoungulate (Nesodon), #litoptern, #astrapothere
@happydogatEUC Speaking of limbs... here are some South American #litoptern feet on display @AMNH for #FossilFriday
#FossilFriday Beautiful #Miocene #Litoptern mandible from #Bolivia - manuscript in process with @ucsantabarbara grad student Andrew McGrath!
