fossa,

carnivorous mammal, Cryptoprocta ferox, of Madagascar. The island's largest carnivore, the fossa resembles a pumapuma
or cougar
, New World member of the cat family, Puma concolor. Also known as mountain lion, catamount, panther, and painter, it ranges from S British Columbia to the southern tip of South America. The puma is slenderly built, with a lionlike face.

 in appearance and has semiretractable claws, but it is most closely related to Madagascar's other native carnivores and to the mongoosemongoose,
name for a large number of small, carnivorous, terrestrial Old World mammals of the civet family. They are found in S Asia and in Africa, with one species extending into S Spain.

 and civetcivet
or civet cat,
any of a large group of mostly nocturnal mammals of the Old World family Viverridae (civet family), which also includes the mongoose. Civets are not true cats, but the civet family is related to the cat family (Felidae).

. Its slender body may be more than 5 ft (1.5 m) long including the tail, which makes up about half of the total length, and the largest males may weigh as much as 26 lb (12 kg). The female is somewhat smaller. The coat is generally reddish brown above and cream below.

The fossa is found in both humid and dry forests and is an agile climber. A generally solitary animal, it preys on lemurs, wild pigs, and other mammals as well as fish and birds; it hunts by ambush. During mating season several males compete for a female, who rests high in a tree; the tree may be used for mating, and then used as a mating ground by another female when the first leaves. There are two to four young in a litter. The young are blind and helpless when born, and remain the mother for about a year and a half. Largely because of habitat destruction, the fossa is endangered.

The fossa is classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Fossa

 

(Cryptoprocta ferox), a predatory mammal of the family Viverridae. The body measures as much as 76 cm in length and as much as 37 cm in height; the tail measures approximately 65 cm in length. The fossa, the largest predator of the island of Madagascar, has a massive body with relatively long, thick extremities and semiretractile claws. It somewhat resembles a cat, but the head is longer. The fur is short, smooth, and reddish brown.

The fossa inhabits forests and feeds on birds and small mammals. It is terrestrial but may climb trees when chasing lemurs. It is active at night. The animal attacks domestic fowl and young domestic swine.

In the Galliformes there is a connection in the temporal fossa, formed by the postorbital process and a calcified aponeurosis located in the rostral extremity of the zygomatic process, indicating that the larger the deposit of calcium salts, the larger the fusion of these structures in the adults will be, contrasting with the absence of this fusion in the young ones (LIVEZEY; ZUSI, 2007).
nebulosa was also on the positive end of PC2, mainly due to a wider zygomatic arch, larger temporal and masseteric muscle advantage, longer temporal fossa and wider braincase.
CT scan showed features similar to her CT scan 4.5 years before, but now the mass showed more widespread infiltration of the right orbit, extension to the temporal fossa, and a lucent area (corresponding to the palpable cutaneous mass) in the temporal fossa (Fig.
Further clinical examination of animal revealed trismus and hollowing of temporal fossa suggestive of muscle atrophy resulting in skull like contour of head (Fig.1).
The temporal fossa was deep and extensive as distinguished by Sharma (2006) in kagani goat; whereas it was described to be wider in ox (Raghavan).
Ill-defined increased T2W signal intensity and enhancement were seen in right TMJ, right temporal fossa, right infratemporal fossa, right parotid gland, right malar, and preauricular region of face indicating extraosseous infiltration (Figures 5(b) and 5(f)).
The temporal fossa is short and high with a length of 114 mm from occipital crest to the anterior border of the temporal fossa.
Posterosuperiorly it communicates with infra temporal fossa. Parapharyngeal space is of special importance for several reasons like complex anatomy, its close proximity to vital anatomical structures and the various complex surgical approaches.
The pterion is an irregular H shaped sutural confluence in the temporal fossa of the skull formed by the frontal, parietal, sphenoid and temporal squama (Williams et al., 1998).
Echocardiography was normal, Magnetic Resonance Imaging (MRI) of orbits and brain showed the presence of Hemangioma in left temporal fossa and periorbital soft tissues with intraorbital extension and coloboma of left eye, hypoplastic left cerebellar hemisphere and left unilateral megalencephaly with prominent sulci/cisterns.
