Skull of a Parksosaurus

Leaellynasaura amicagraphica, dinosaur, skull. Holotype. [P 185991]

Skull reconstruction of Incisivosaurus gauthieri.

Sarcosaurus diagram of known material: reconstruction based on basal Ceratosaurs (such as Berberosaurus and Saltriovenator). The Skull was made to look more generic and less like more derived Ceratosaurs such as Ceratosaurus. "Liassaurus", referred to "cf. Sarcosaurus woodi" and is smaller than the holotype: material in light grey is preserved, but to what extent is uncertain as it is not figured. References: Carrano and Sampson (2004).

Mounted holotype skull (IVPP V725) of T. spinorhinus in left lateral view (reversed). F. Partial right distal nasal process (although catalogued as IVPP V725, this element corresponds to a different specimen than the type; reversed).

The nodosaurid dinosaur, Glyptodontopelta is mostly known from isolated osteoderms ("armor plates"). The specimen SMP VP-1580 (State Museum of Pennysylvania) is however, the most complete known specimen, comprising parts of the skull, hundreds of osteoderms and fragments. This specimen was discovered in 2003 by Warwick Fowler, in the Naashoibito Member of the Ojo Alamo Formation (Maatrichtian, Late Cretaceous) of the San Juan Basin, New Mexico, during an expedition led by Dr. Robert Sullivan.

Reconstruction and restoration of the skull of Eolambia. (A) Skull reconstruction of Eolambia in left lateral view by the lead author. Bones in white are unknown, bones in dark grey are based primarily upon the adult holotype (CEUM 9758) or paratype (CEUM 5212), and bones in light grey are based primarily upon juvenile elements from the Eo2 and WS8 bonebeds. Sutures and points of contact between bones are marked in black. Scale bar equals 10 cm; scale is calibrated with the dentary of CEUM 9758. (B) Life restoration of the head of Eolambia by Lukas Panzarin. Abbreviations: an, angular; d, dentary; f, frontal; j, jugal; l, lacrimal; mx, maxilla; na, nasal; pd, predentary; pmx, premaxilla; po, postorbital; prf, prefrontal; q, quadrate; qj, quadratojugal; sa, surangular; sq, squamosal.

Skeletal reconstruction of Stenonychosaurus, based on all known material, with missing parts of the skull and vertebral column based on Saurornithoides.[1] This version is modified from a version which was itself modified with red colour to show the known parts of the new genus Talos.
