SPECIMENS USED:
Deltadromeus agilis - SGM-Din2 (Sereno et al. 1996)
Gualicho shinyae - MPCN PV 0001 (Apesteguía et al. 2016)
Masiakasaurus knopfleri - FMNH PR 2481 (Carrano et al. 2002; Carrano et al. 2011), FMNH PR 2485 (Carrano et al. 2002; Carrano et al. 2011), and their referred isolated specimens.
Elaphrosaurus bambergi - MB R 4960 (Rauhut & Carrano, 2016)

BONES USED:
Skull - Speculative composite based off available data for Masiakasaurus (Carrano et al. 2002; Carrano et al. 2011).

Vertebrae - Atlas speculative. Cervical vertebrae modified from Masiakasaurus (Carrano et al. 2011). Anterior dorsal vertebrae restored from Masiakasaurus. Posterior dorsal vertebrae composites based on Deltadromeus neural spines (Sereno et al. 1996) and Elaphrosaurus centra (Rauhut & Carrano, 2016). Anterior and caudal vertebrae composites based on Deltadromeus neural spines (Sereno et al. 1996) and Elaphrosaurus centra (Rauhut & Carrano, 2016). Distal caudals speculative.

Ribs - Cervical ribs mostly speculative, with only the 6th represented in Masiakasaurus (Carrano et al. 2011). Dorsal ribs speculative. Gastralia based on Gualicho (Apesteguía et al. 2016).

Pectoral girdle - Scapulocoracoid restored after known elements from Deltadromeus (Sereno et al. 1996) and Gualicho (Apesteguía et al. 2016). Sternal elements speculative. Furcula speculative.

Arms - Humerus from Deltadromeus (Sereno et al. 1996). Forearm and hand from Gualicho (Apesteguía et al. 2016).

Pelvic girdle - Ilium modified from Masiakasaurus (Carrano et al. 2011). Ischium modified from Masiakasaurus (Carrano et al. 2011). Pubis composite from Deltadromeus (Sereno et al. 1996), Gualicho (Apesteguía et al. 2016) and Masiakasaurus (Carrano et al. 2002; Carrano et al. 2011).

Leg - Femur based on Deltadromeus (Sereno et al 1996). Tibia and fibula modified from Gualicho (Apesteguía et al. 2016) and Elaphrosaurus (Rauhut & Carrano, 2016). Foot restored from Gualicho (Apesteguía et al. 2016) and Masiakasaurus (Carrano et al. 2002; Carrano et al. 2011). Hallux and metatarsal V speculative.
