Exempel på hur man kan använda OSTEODERMS i en mening

• Common characteristics of this group include a reduced supratemporal arch, striations on the medial faces of tooth crowns, osteoderms, and a lateral fold in the skin of most taxa.
• They defend themselves with osteoderms (flat bony plates in the skin) and by quickly retreating into rock crevices or burrows.
• Six species of Pseudocordylus are known; they are distinguished from girdled lizards of the genus Cordylus by the presence of granular scales on the back instead of osteoderms.
• Fossil evidence from some varanopids shows that parts of the skin were covered in rows of osteoderms, presumably overlain by horny scutes.
• Primitive forms had simple, low, keeled scutes or osteoderms, whereas more derived forms developed more elaborate structures including spikes and plates.
• Under the scales there are bony plates (osteoderms), so that slow worms crawl much more stiffly and clumsily than snakes.
• Reed collected a partial postcranial skeleton (YPM VP 1815) on July 17, 1881 southeast of the productive Quarry 13, the skeleton including: 3 dorsal and 13 caudal vertebrae, 3 dorsal ribs, fragmentary forelimbs, a partial pelvis, femora, tibiae, partial left pes, and several osteoderms.
• The osteoderms, also known as dermal scutes, of Sarcosuchus were similar to those goniopholodids like Sunosuchus and Goniopholis; they formed an uninterrupted surface that started in the posterior part of the neck down to the middle of the tail as is seen in Araripesuchus and other basal crocodyliforms; this differs from the pattern seen in living crocodiles, which presents discontinuity between the osteoderms of the neck and body.
• When compared with Anodontosaurus and Scolosaurus, Euoplocephalus lacks round osteoderms at the base of the squamosal and quadratojugal horns.
• Utterback, yielded further fossils, including additional osteoderms, as well as vertebrae, ribs, and a pubis.
• Mylodontids are the only ground sloths confirmed to have osteoderms embedded within their skin, though osteoderms were only present in a handful of genera (Mylodon, Paramylodon and Glossotherium) and absent in others.
• Armadillos have dorsal armor that is formed by osteoderms, plates of dermal bone covered in relatively small, overlapping keratinized epidermal scales called "scutes".
• It is rectangular, adorned by large triangular osteoderms: up to twelve episquamosals at the squamosal and three epiparietals at the parietal bone.
• It features four horizontal rows of larger keeled osteoderms per side, surrounded by smaller ossicles.
• The osteoderms on the side of the tail, the knob itself excepted, have a front edge with a strongly hollow profile, while their points are off-set to the rear.
• Dissorophids are most readily recognized for their distinctive osteoderms, although these are not unique to either dissorophids among temnospondyls or to temnospondyls among early tetrapods.
• Although temnospondyls are amphibians, many had characteristics such as scales and large armour-like bony plates (osteoderms) that generally distinguish them from the modern soft-bodied lissamphibians (frogs and toads, newts, salamanders and caecilians).
• Around 1865, commercial fossil collector John Griffiths found some dinosaurian remains, including osteoderms, at the shoreline near Folkestone in Kent, which he sold to the metallurgist Dr.
• Rectangular in shape, the frill is edged by large epoccipitals, which are osteoderms in the form of triangular bony projections.
• a shoulder blade, a coracoid, a humerus, a thighbone, foot bones, a cervical halfring and osteoderms.
