Megapnosaurus is a coelophysid theropod dinosaur from the Early Jurassic Period of Africa. It was a lightly built bipedal carnivore that grew to just over 2 m long and 13 kg in body mass. Its close relation to Coelophysis has caused some confusion in classifying the genus - it had a slender build and curved S-shaped neck, but was more robust. Comparisons between the scleral rings of Megapnosaurus and modern birds and reptiles indicate that it may have been nocturnal.

The titanosaurian sauropod Lirainosaurus astibiae Sanz, Powell, Le Loeuff, Martínez, and Pereda Suberbiola, 1999 from the Late Cretaceous of Laño (northern Spain), paratypic braincase (MCNA 7439). Right lateral, left lateral, posterior, and anterior views.
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.

In 2000 a virtually complete Scelidosaurus skeleton was discovered in England. This fossil's hundreds of armor plates and spikes are preserved in their life positions, providing extraordinary details about how this dinosaur looked. St. George is the only place anywhere in the Western Hemisphere that the 11-foot long Scelidosaurus replica has been on display. The St. George Dinosaur Discovery Site at Johnson Farm (St. George, Utah) is home to exceptionally well-preserved dinosaur tracks, some displaying skin impressions. These tracks, along with hundreds of fossil fish, plants, rare dinosaur remains, invertebrates traces and important sedimentary structures, show evidence that this site was produced along the western edge of a large, Early Jurassic (age between 195-198 million years ago) freshwater lake named Lake Dixie.
