Cranial morphology of the tanystropheid Macrocnemus bassanii unveiled using synchrotron microtomography

Scientific Reports, 2020
The genus Macrocnemus is a member of the Tanystropheidae, a clade of non-archosauriform archosauromorphs well known for their very characteristic, elongated cervical vertebrae. Articulated specimens are known from the Middle Triassic of Alpine Europe and
