The platypus (Ornithorhynchus anatinus), [4] sometimes referred to as the duck-billed platypus, [5] is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus Ornithorhynchus , though a number of related species ...
This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts. The ornithopod family, which includes genera such as Edmontosaurus and Parasaurolophus , was a common group of herbivores during the Late Cretaceous Period . [ 1 ]
Both the platypus and echidna species have spurs on their hind limbs. The echidna spurs are vestigial and have no known function, while the platypus spurs contain venom. [ 42 ] Molecular data show that the main component of platypus venom emerged before the divergence of platypus and echidnas, suggesting that the most recent common ancestor of ...
The platypus uses its super-sensitive bill to find its dinner. A platypus bill may look like a duck’s bill, but it has a secret ability. ... While the echidna species has 400 to 2,000 ...
The platypus, a duck-billed, beaver-tailed mammal that adores the water, is so beloved in its home country of Australia, the nation has featured the species on its 20-cent coin.
Hadrosauroidea is a clade or superfamily of ornithischian dinosaurs that includes the "duck-billed" dinosaurs, or Hadrosauridae, and all dinosaurs more closely related to them than to Iguanodon. Their remains have been recovered in Asia, Europe, Africa and the Americas.
This contrasts with the modern platypus, where adults are entirely toothless. It has been theorized that the loss of teeth in the platypus was a geologically recent event, occurring only in the Pleistocene (after over 95 million years of tooth presence in the ornithorhynchid lineage) after the migration of the rakali ( Hydromys chrysogaster ...
The four extant species of echidnas and the platypus are the only living mammals that lay eggs and the only surviving members of the order Monotremata. [3] The diet of some species consists of ants and termites, but they are not closely related to the American true anteaters or to hedgehogs. Their young are called puggles.
