A skull diagram of the titanosaur Antarctosaurus wichmannianus showing known areas in white and unknown areas in grey. The remains attributed to A.wichmannianus are of questionable referral, the association of the described elements and therefore, this reconstruction are not certain. It is possible that the mandible and rear parts of the skull do not belong to the same individual or even genus.[1] This image assumes they do belong to the same individual. • Known skull elements based on the illustrations in Huene (1929).[2] Unknown areas inspired by Figure 7 in Gallina & Apesteguia (2011) and other titanosaur skull reconstructions.[3] The size of the sclerotic ring is speculative.

From the permanent collection of The Judith River Foundation, Leonardo, a fully articulated and partially mummified skeleton of a subadult brachylophosaur, is currently on loan to The Children’s Museum of Indianapolis. The fossil is 77 million years old and was discovered in Montana in 2000.

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 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.
