Sorry, no etymologies found.
A new mammaliaform from the Early Jurassic and evolution of mammalian characteristics.
In May 2001 Zhe-Xi Luo and colleagues described Hadrocodium, a new basal mammaliaform from Lower Jurassic China.
Yesterday I was asked if Megazostrodon (a basal mammaliaform from Lower Jurassic Lesotho) should be depicted with ‘ear flaps’ (= pinnae).
It’s generally agreed that Megazostrodon is right down at the base of Mammaliaformes, and thus, under current convention, outside of the mammaliaform crown-group Mammalia.
Of course we don’t really know whether they had fur either (despite dubious suggestions of evidence for such structures in non-mammaliaform synapsids), but it’s reasonable to think that they did given that, phylogenetically, they’re very close to the mammalian common ancestor (and, again, on the basis of parsimony that animal would have been furry), and not all that different from basal mammals.
