Limb bones: thirty-four osteoderms
(ROM-4057240599, 40620, 40600-40604 and 42190); one podial bone (ROM-40620).
The scientists found parts of its skull, lower jaw, neck and back vertebrae, ribs, shoulder and forelimb, back foot and osteoderms
, which were enough to help us draw the imaginative image of the dinosaur and help us to know its genus.
Like many titanosaurs, Mansourasaurus boasted bony plates called osteoderms
embedded in its skin.
It had large nostrils and elaborate ornamentation across the snout," which helped identify the species as different from previously known members of the group, all of which had bony spikes, called osteoderms
However, none of these studies mentioned what type of bone remains allowed the identification of the species listed above, except Quintela and Gatti (2009) that reported the presence of osteoderms
of armadillos in the feces analyzed.
Goniopholidids are one of the most common taxa of the crocodylomorph European Mesozoic fossil record (Buscalioni et al., 2013) and teeth and osteoderms
are dominant remains in fossil assemblages (Schwarz, 2002; Salisbury and Naish, 2011).
The holotype of Scoloparia glyphanodon (NSM996GF83.1) has a 'nuchal shield' composed of small, polygonal osteoderms
, but no other known specimen preserves this distinctive feature (Sues and Baird 1998).
In Glyptotherium, hundreds of small osteoderms
, also known as scutes, make up a typical carapace.
Stegosaurus was covered in osteoderms
, which are bony deposits on the skin that acted as armor.
This fossil deposit was dated between 25.5 [+ or -]0.6 and 27.98 [+ or -]0.37KaBP by accelerator mass spectrometry, using collagen extracted from Xenarthra osteoderms
(Jull et al., 2004).
According to a team of researchers from the University of Guelph, the study of two sauropod dinosaurs, an adult and a juvenile, from Madagascar, suggested that these long-necked plant-eaters used hollow "skin bones" called osteoderms
to store minerals needed to maintain their huge skeletons and to lay large egg clutches.
Smaller, relatively elongate and irregular coprolitic masses are of more typical crocodylian fecal morphology and may come from Borealosuchus sp., also represented by bones, teeth, and osteoderms
in the fossil assemblage.
