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.

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

(foss -ă) (plural: fossae) a long narrow shallow depression. The word is used in the approved name of such a surface feature on a planet or satellite.

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.

Recreating large-scale, unique Madagascan habitats for rare lemurs and fossa, right here in Chester, is an important part of our global conservation plan.
In this regard, 3 different cases of the study have been considered for the numerical evaluation of the contact stresses at the prosthesis interface, that is, at the contact surface between the glenoid fossa and the mandibular components.
The patient's intraoperative course lasted approximately eleven hours during which time the patient underwent a left middle fossa craniotomy, TMJ arthroplasty, glenoid fossa reconstruction with split-thickness calvarial bone graft, and maxillomandibular fixation.
For pyriform fossa tumours it is 3.6: 1, but for postcricoid tumours it is 1: 2.
During our routine dissection classes for undergraduate medical students, we observed neurovascular variations in the infratemporal fossa. Accessory meningeal artery arose from the middle meningeal artery, 25 mm below the base of the skull and entered the middle cranial fossa through the foramen ovale by passing behind the mandibular nerve.
The defects were successfully repaired with temporal muscle fascia or fascia lata graft and fibrin glue using the middle cranial fossa approach via craniotomy.
Fossa are their own unique species, but closely related to Mongoose and meercats.

Computed tomography (CT) showed a soft-tissue mass that had destroyed the bony plate of the posterior and middle cranial fossa (Figures 2(a) and 2(b)).
Therefore a CT arthrogram was ordered identifying a 4.5 x 2.4 x 1cm lesion expanding medially through the acetabular fossa but respecting its inner table.
Although a nonrecognizable cerebellar hemisphere in the posterior fossa mimicked primary cerebellar agenesis [4], T2 star-weighted angiography (SWAN) successfully detected hemosiderin deposits enveloping the cystic lesion, which led to the diagnosis of an acquired form of DWM and selection of a surgical intervention approach.
