Compsognathus corallestris (Bidar et al. 1972b; Peyer 2006; CNJ79) is a bit larger with a different morphology (Fig. 1) than the coeval smaller Bavarian Solnhofen specimen, Compsognathus longipes (Fig. 1 right). Dr. Peyer considers these two Late Jurassic theropods conspecific and representative of ontogenic rather than phylogenetic variation. This specimen nests basal to the oviraptorid clade, but remains a sister to the holotype.

Masiakasaurus knopfleri (Sampson, Carrano and Forster 2001; Carrano, Loewen and Sertic 2011; Late Cretaceous) was originally considered a bizarre predatory dinosaur related to abelisaurids, like giant Majungasaurus. In the LRT Masiaksaurus is related to The CNJ9 specimen assigned to Compsognathus (above), which also has procumbent teeth and a long torso. Essentially this is a large compsognathid.
