It is situated in the middle of the skull towards the front, in front of the basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit . Its shape somewhat resembles that of a butterfly , bat or wasp with its wings extended.
[7] [8] The oldest complete bat skeleton is Icaronycteris gunnelli (52 million years ago), known from two skeletons discovered in Wyoming. [9] [10] The extinct bats Palaeochiropteryx tupaiodon and Hassianycteris kumari, both of which lived 48 million years ago, are the first fossil mammals whose colouration has been discovered: both were ...
The dorsum sellae is part of the sphenoid bone in the skull.Together with the basilar part of the occipital bone it forms the clivus.. In the sphenoid bone, the anterior boundary of the sella turcica is completed by two small eminences, one on either side, called the middle clinoid processes, while the posterior boundary is formed by a square-shaped plate of bone, the dorsum sellae, ending at ...
The order Chiroptera, comprising all bats, has evolved the unique mammalian adaptation of flight.Bat wings are modified tetrapod forelimbs. Because bats are mammals, the skeletal structures in their wings are morphologically homologous to the skeletal components found in other tetrapod forelimbs.
Skull of the greater horseshoe bat, showing the prominent rostral inflation on the snout. All horseshoe bats have large, leaf-like protuberances on their noses, which are called nose-leafs. [10] The nose-leafs are important in species identification, and are composed of several parts. [20]
A bat wing, which is a highly modified forelimb. Bats are the only mammal capable of true flight. Bats use flight for capturing prey, breeding, avoiding predators, and long-distance migration. Bat wing morphology is often highly specialized to the needs of the species. This image is displaying the anatomical makeup of a specific bat wing.

The Phyllostomidae, also known as New World leaf-nosed bats, are among the most ecologically diverse mammal families. [6] This variation is measured by diversity in skull morphology and diet-related characteristics: Phyllostomidae consists of species that have evolved physical modifications for insectivory, frugivory, hematophagy, nectarivory, and omnivory.
