Mandasuchus tanyauchen, gen. et sp. nov., a pseudosuchian archosaur from the Manda Beds (?Middle Triassic) of Tanzania

摘要: ABSTRACTThe diverse assemblage of extinct archosaur species known from the Manda Beds Tanzania has provided key insights into timing and tempo early part radiation during Middle Triassic. Several specimens were collected in 1933 by F. R. Parrington, three these subsequently described made basis a new genus, ‘Mandasuchus,’ 1956 doctoral dissertation. However, this important fossil material was never formally published, >60 years later ‘Mandasuchus’ ‘Mandasuchus tanyauchen’ remain nomina nuda, despite frequent references to them literature. Here, we provide detailed description material, first formal diagnosis Mandasuchus tanyauchen, gen. et sp. nov., assess its phylogenetic position. The holotype M. tanyauchen includes well-preserved partial postcranial skeleton fragmentary cranial remains. Four referred include two skeletons, consisting primary...
