introduces Wachtlerosaurus ladinicus (Fig. 1, 2), a tiny disarticulated reptile from the Middle Triassic Dolomites of northern Italy. Perner considers the specimen an archosaur. In the large reptile tree (LRT, 1264 taxa) the specimen nests with thalattosaurs and Thalattosaurus in particular. The purported antorbital fenestra is the naris.
The Dolomites are about 250 million years old
and are formed from coral reefs in the Tethys Sea, a perfect niche for a marine reptile like a thalattosaur.
A reconstruction of the skull helps
(Fig. 1) put the pieces of the broken skull back together again.
A few other new interpretations on the paper.
- Perner 2018 identifies two long, parallel dorsal ribs surrounding a jumble of ?vertebrae as parts of an oversized pelvis (Fig. 1).
- Perner employs the humerus in place of a scapula (Fig. 1).
- Probably this scattered bone specimen is incomplete, not nearly complete, as described.
