Updated February 28, 2015 with a new skull for Daemonosaurus.
Earlier the large reptile tree nested Daemonosaurus at the base of the Ornithischia (more primitive than Scelidosaurus), not far from Pampadromaeus, Thecodontosaurus and Sacisaurus, among the other phytodinosaur clades. After learning about the palate of Heterodontosaurus, gaining new insights into Pantydraco and revising the scoring of several dinosaur taxa (thanks M. Mortimer), I traced another DGS illustration and created a new reconstruction.
See, I’m always ready to change and ready to learn.
And there’s still more to learn, I’m sure. Here are the new in situ images.
The intermediate length cervicals suggest Daemonosaurus had a neck, midway between that of a typical ornithischian and sauropodomorph.
Daemonosaurus has a high naris, like Herrerasaurus and Massospondylus. The narial depression drops first, then the naris follows on other taxa.
Daemonosaurus has a shorter rostrum than Herrerasaurus and shorter than Pampadromaeus, but not as short as the phytodinosaurs.
The descending quadrate and quadratojugal in Daemonosaurus are also found in Heterodontosaurus and others.
