Oryctolagus (/ ˌ ɔː r ɪ k ˈ t ɑː l ə ɡ ə s /) is a genus of lagomorph that today contains the European rabbit and its descendant, the domestic rabbit, as well as several fossil species. The generic name derives from Ancient Greek : ὀρυκτός ( oryktos , “dug up”) and λαγώς ( lagōs , “hare”).
Fossil occurrences of leporids and ochotonids and global environmental change (climate change, C 3 /C 4 plants distribution) [2]. The lagomorphs (/ ˈ l æ ɡ ə m ɔː r f /) are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae (rabbits and hares) and the Ochotonidae ().
The domestic rabbit (Oryctolagus cuniculus domesticus) is the domesticated form of the European rabbit, a member of the lagomorph order. A male rabbit is known as a buck, a female as a doe, and a young rabbit as a kit. There are hundreds of rabbit breeds, originating from all over the world.
The squamosal is a skull bone found in most reptiles, amphibians, and birds. In fishes, it is also called the pterotic bone. [1] In most tetrapods, the squamosal and quadratojugal bones form the cheek series of the skull. [2] The bone forms an ancestral component of the dermal roof and is typically thin compared to other skull bones. [3]
The jugal bone is located on either side of the skull in the circumorbital region. It is the origin of several masticatory muscles in the skull. [1] The jugal and lacrimal bones are the only two remaining from the ancestral circumorbital series: the prefrontal, postfrontal, postorbital, jugal, and lacrimal bones. [2]
Classic comparative anatomy have regarded the interparietal as being lost in various mammalian lineages since the interparietal and supraoccipital fuse with each other in the early ontogenetic period in many mammals, but recent study has shown that its presence is confirmed in all extant mammalian orders, particularly in the embryonic period ...
Unlike the erect ear of the majority of domestic rabbit breeds, lop breeds have ears loosely drooping, with the opening of the ear facing the skull. Due to the slightly-raised cartilaginous ear base, the head of many lop rabbits (with the exception of English Lops ) has a small bulge, referred to as the crown .
