Yet, it differs markedly from Late Triassic silesaurids in dental and vertebral anatomy. Indeed, a detailed redescription of its holotype allowed the identification of several features of the skeleton previously unrecognized amongst silesaurids. These include pterygoid teeth, a dorsomedial posttemporal opening on the otoccipital, foramina associated with cranial nerves X–XII on the caudal region of the prootic–otoccipital, and postaxial neck/trunk vertebrae with craniocaudally expanded neural spines. The presence of a single row of presacral scutes was also confirmed. Some elements previously referred to, or found associated with, the holotype, including a lower jaw, pedal elements and an astragalus, more probably correspond to proterochampsid remains. The anatomical information available for the holotype of \u003ci\u003eL. admixtus\u003c/i\u003e was rescored into a new phylogenetic dataset for dinosauromorphs, mostly based on previous works. \u003ci\u003eLewisuchus admixtus\u003c/i\u003e and \u003ci\u003ePseudolagosuchus major\u003c/i\u003e are treated as distinct OTUs because their preserved skeletons mostly lack overlapping parts. The parsimony analysis supports the basal position of \u003ci\u003eL\u003c/i\u003e. \u003ci\u003eadmixtus\u003c/i\u003e within dinosauriforms, prior to the silesaurid–dinosaur split, rather than at the base of Silesauridae. This suggests that a higher number of early dinosauriform clades branched in the Middle and Late Triassic than previously suggested.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://tandf.figshare.com/articles/dataset/Osteology_of_the_Middle_Triassic
