A vulture is a bird of prey that scavenges on carrion.There are 23 extant species of vulture (including condors). [2] Old World vultures include 16 living species native to Europe, Africa, and Asia; New World vultures are restricted to North and South America and consist of seven identified species, all belonging to the Cathartidae family.
A subclass of the Osteichthyes, the ray-finned fish (Actinopterygii), have become the dominant group of fish in the post-Paleozoic and modern world, with some 30,000 living species. The bony (and cartilaginous) fish groups that emerged after the Devonian were characterised by steady improvements in foraging and locomotion.
The turkey vulture (Cathartes aura) is the most widespread of the New World vultures. [2] One of three species in the genus Cathartes of the family Cathartidae, the turkey vulture ranges from southern Canada to the southernmost tip of South America. It inhabits a variety of open and semi-open areas, including subtropical forests, shrublands ...
The evolution of fishes took place over a timeline which spans the Cambrian to the Cenozoic, including during that time in particular the Devonian, which has been dubbed the "age of fishes" for the many changes during that period. The Late Devonian extinctions played a crucial role in shaping the evolution of fish, or vertebrates in general. [1]
Some species of New World vulture have a good sense of smell, whereas Old World vultures find carcasses exclusively by sight. Other adaptations shared by both Old and New World vultures include a bald head , devoid of feathers which prevents rotting matter from accumulating while feeding, and an extremely disease-resistant digestive system to ...
A newfound fossil of a jawless fish is the oldest known vertebrate cranium preserved in 3D. The 455 million-year-old find could illuminate how vertebrate heads evolved.
The vulture's glyph is often shown attacking humans. This species lacks the religious connections that the king vulture has. While some of the glyphs clearly show the black vulture's open nostril and hooked beak, some are assumed to be this species because they are vulture-like but lack the king vulture's knob and are painted black.
