The most recognizable feature of Armadillosuchus is its body armor, which makes it one of the best armored notosuchians. Preserved elements show the presence of a rigid shield of hexagonal osteoderms just behind the head, followed by a series of mobile bands similar to those of armadillos that give the animal its name.
This dermal armor is found prominently in many lizards. Some early amphibians have this armor, but it is lost in modern species with the exception a ventral plate, called the gastralia. [3] [4] Osteoderm demonstrates a slightly delayed development compared with the rest of the skeleton, as it does not appear until after hatching has occurred.
Armadillos have dorsal armor that is formed by osteoderms, plates of dermal bone covered in relatively small, overlapping keratinized epidermal scales called "scutes". Most species have rigid shields over the shoulders and hips, with three to nine bands separated by flexible skin covering the back and flanks.
The word armadillo means ' little armored one ' in Spanish; [2] [3] it is derived from armadura ' armor ', with the diminutive suffix -illo attached. While the phrase little armored one would translate to armadito normally, the suffix -illo can be used in place of -ito when the diminutive is used in an approximative tense. [4]
Glyptodon (lit. ' grooved or carved tooth '; from Ancient Greek γλυπτός (gluptós) 'sculptured' and ὀδοντ-, ὀδούς (odont-, odoús) 'tooth') [1] is a genus of glyptodont, an extinct group of large, herbivorous armadillos, that lived from the Pliocene, around 3.2 million years ago, [2] to the early Holocene, around 11,000 years ago, in South America.
The nine-banded armadillo has been rapidly expanding its range both north and east within the United States, where it is the only regularly occurring species of armadillo. The armadillo crossed the Rio Grande from Mexico in the late 19th century, and was introduced in Florida at about the same time by humans.
Arrangement of armor as suggested by Arbour and Mallon, 2017. A prominent feature of Ankylosaurus was its armor, consisting of knobs and plates of bone known as osteoderms, or scutes, embedded in the skin. These have not been found in articulation, so their exact placement on the body is unknown, though inferences can be made based on related ...
The southern three-banded armadillo (Tolypeutes matacus), also known as La Plata three-banded armadillo or Azara's domed armadillo, [2] is an armadillo species from South America. [3] It is found in parts of northern Argentina , southwestern Brazil , Paraguay and Bolivia , at elevations from sea level to 770 m (2,530 ft).
