Dolerosaurus

Dolerosaurus is an extinct genus of diapsid known from the early Late Triassic (late Carnian stage) upper Lunz Formation of Austria. "Dolerosaurus" was first named by Richard J. Butler in 2013 and the type species is "Francosuchus trauthi".
Discovery and naming.
In 1939 Friedrich von Huene named a new species of the phytosaur "Francosuchus", "F. trauthi", based upon a small fragment of rostrum. It was at some point later referred to "Paleorhinus", but in 2013, it was renamed to the new genus "Dolerosaurus". Unfortunately very little can be said about "Dolerosaurus" given that its holotype fossil is so small (c. long) and the known remains are so scant. "Dolerosaurus" was referred to phytosauria in 1939, but after subsequent analyses in 2013, it was reclassified as a basal diapsid.
