- ... that an unnamed member of the extinct order Hupehsuchia exhibited an unusual form of polydactyly that is similar to that of some early tetrapods of the Devonian period?
- ... that the Triassic reptile Vancleavea, which is specialized to live in the water, differs greatly from all other earlyarchosauriforms?
- ... that although it was first classified as a reptile, the extinct genus Batropetes (restoration pictured) is now known to be a microsaur amphibian?
- ... that the Late Triassic archosauromorph Uatchitodon is the earliest known venomous reptile?
- ... that, in one study on the aetosaur Redondasuchus, the orientation of a diagram in the paper may have contributed to the misidentification of its holotype as a left scute rather than a right?
