This is one of the weirdest, most profoundly modified skeletal plans in the whole of Tetrapoda: it is, we think, highly specialised for jumping, and the inheritance and retention of this bauplan means that anurans are, as a group, rather uniform. ![]() The tibia and fibula are fused together, forming another compound structure termed the tibiofibula, while the proximal tarsal bones have become elongate, tibia- and fibula-like structures (termed the tibiale and fibulare) that effectively function as an additional limb segment. A midline element present in anuran ancestors – the interclavicles – is absent.Īnuran hindlimbs are generally highly elongate. The omosternum and xiphisternum appear to be new structures that might have a role in shock absorption. Both a cleithrum and a cartilaginous suprascapula are present dorsal to the scapula (Havelková & Roček 2006): the anuran cleithrum is a relict and much less important in size and shape than it is in temnospondyls and other fossil relatives of anurans. In others, the epicoracoid cartilages are fused at the midline, forming the firmisternal condition. In some anurans, the epicoracoid cartilages are obviously paired and both components distinctly overlap on the midline, forming what’s known as the arciferal condition. The omosternum projects anteriorly from the junction of the clavicles, and the procoracoids are attached to both the posterior margins of the clavicles and the epicoracoid. The paired clavicles and coracoids are transverse bars, separated along the midline by the epicoracoid cartilages and sternum/xiphisternum. Meanwhile, the bones of the pectoral girdle are complex and complimented by an assortment of new elements.

A clear dome on top completes the casing this specimen makes for a lovely display. catesbeiana skeleton is finely articulated and mounted onto a polished compressed-wood base. ![]() The bullfrog generally reaches between 3.6 and 6 inches in length from snout to vent. The species is native to the United States and Canada, but has been widely introduced across the rest of the Americas, Europe, and Asia, and is regarded as an invasive one in some areas. Males are known to be aggressive and territorial, especially during breeding season (albeit being smaller on average than females), and have a distinct call reminiscent of the roar of a bull- hence its common name. ![]() It inhabits large, permanent bodies of water including swamps, ponds, and lakes, and can usually be found along the water’s edge. Its upper lip is often bright green, and males boast striking yellow throats. This frog has an olive green back, sides blotched with brown markings, and a whitish belly with grey and/or yellow spots. ![]() The American bullfrog, often known simply as the bullfrog in Canada and the United States, is a species of amphibian in the Ranidae family (true frogs).
