Looking at their anatomy, I quickly realized that millerettids shared more features with neodiapsid reptiles, particularly in their braincase and postcranial skeleton.

The origin of the tympanic fossa in reptiles revealed by a late Permian neodiapsid: new species Scyllacerta creanae onlinelibrary.wiley.com/doi/10.1111/... #FossilFriday @semifossorial.bsky.social @morphobank.bsky.social
Top left: photograph of a grey slab containing multiple fossils, with vertebral columns clearly running vertically (SAM-Pk-K7710). This is a group of six Scyllacerta creanae individuals, including the holotype, a late Permian neodiapsid reptile from South Africa (scale bar at top right is 2 cm). Bottom right: a computer reconstruction of the skull based on three of the individuals in the fossil block. Scale bar at top right is 5 mm.

Thadeosaurus colcanapi - an enigmatic lizard-like reptile from the Late Permian of Gondwana onlinelibrary.wiley.com/doi/10.1002/... #PapersinPalaeontology
An artistic reconstruction of the enigmatic neodiapsid Thadeosaurus colcanapi from the upper Permian of Madagascar. The grey lizard-like animal with a long banded tail stands on a rock with water in the background and vegetation rich in Glossopteris (a leaf of which is present on the fossil material). Illustration by Sophie Fernandez (MNHN).

That question led Valentin Buffa @valentinbuffa.bsky.social and I to re-examine all non-saurian neodiapsid taxa.

And we found tympanic fossae in more places than expected…. Even Youngina!
Phylogeny of early reptiles showing the placement of Scyllacerta as an early Younginid and mapping the appearance of the tympanic fossa, loss of lower temporal bar, and appearance of the cephalic Condyle on the quadrate in these taxa.

Our postcranial observations, specifically on the foot, suggests that many features of the modern reptile hindlimb are actually present in their closest fossil relatives!

You heard it folks: milleretids are *also* postcranially very neodiapsid-like 😃

Milleretta also closes a lower temporal fenestra AND a ‘gap’ in the region of the Neodiapsid upper temporal fenestra through ontogeny. This latter feature is diagnostic for all millerettids.

I don’t think that this gap actually represents a UTF, but that Permian reptile skulls are a bit nuanced

The tree as presented in the text figure is reduced to exclude some of the Palaeozoic taxa within the analysis, specifically the younginid-like neodiapsid Orovenator. Those taxa drag divergence dates pretty deep into the Permian and maybe the Carboniferous, depending on where you put them
