@nbtapioles @AndreyAtuchin interpreted Therizinosaur as a plantigrade dinosaur first in Dinosaur Facts and Figures: The Theropods and Other Dinosauriformes. I don't sure if this interpretation is right but I don't think is impossible.
Lewisuchus admixtus is an early dinosauriform from the lower Upper Triassic of Argentina. Recent discovery of 2 partial articulated skeletons provide significant novel information:

First ornithischians or non-dinosaurian dinosauriforms? Silesaurus (top) and Lewisuchus (bottom)
Silesaurus was a rather strange reptile of uncertain taxonomic affinities. Was it a Dinosauriform as is traditionally, or was it an Ornithischian as of a new study? Probably the latter, but hopefully future research reveals more on this strange Triassic creature!
Silesaurus opolensis (Silesia lizard) a genus of silesaurid dinosauriform from the Late Triassic (Carnian Age 230-227 MYA). From Poland (Drawno Beds Formation). Named by Jerzy Dzik in 2003 and was about 2.3 meters (7.5 feet) long.
Finding that segmenting microCT data of the early dinosauriform Marasuchus/Lagosuchus for #DAWNDINOS is just what I need right now. Very relaxing, and my skills have improved a lot, so it's satisfying too. Left hindlimb here; pieces done, now to put it back together in 3D.
Marasuchus lilloensis was a small dinosauriform of Late Triassic Argentina (Chañares Formation) not a dinosaur. The hypothetical crest I used in this reconstruction is meant to be made of some sort of quill-like structures homologous to dinosaur filaments #paleoart #FossilFriday
Also for #FossilFriday, here is Asilisaurus kongwe, a silesaurid dinosauriform from the Mnda Beds, Triassic, Tanzania #paleoart
