Snakebite. A snakebite is an injury caused by the bite of a snake, especially a venomous snake. [9] A common sign of a bite from a venomous snake is the presence of two puncture wounds from the animal's fangs. [1] Sometimes venom injection from the bite may occur. [3] This may result in redness, swelling, and severe pain at the area, which may ...
Spinosaurus (/ ˌspaɪnəˈsɔːrəs /; lit. 'spine lizard') is a genus of spinosaurid dinosaur that lived in what now is North Africa during the Cenomanian stage of the Late Cretaceous period, about 100 to 94 million years ago. [2] The genus was known first from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst ...
Based on specimen QM F10113, the bite force of Kronosaurus is estimated to be between 16,000 to 23,000 newtons (3,600 to 5,170 lbf). [124] Still based on the same specimen, a 2014 Foffa et al. (2014) reestimates the bite force at between 15,000 to 27,000 newtons (3,370 to 6,070 lbf), corresponding to its close Jurassic relative Pliosaurus kevani.
American zoologist Dean Conant Worcester, describing the Bornean slow loris in 1891. The earliest known mention of a slow loris in scientific literature is from 1770, when Dutchman Arnout Vosmaer (1720–1799) described a specimen of what we know today as N. bengalensis that he had received two years earlier. The French naturalist Georges-Louis Leclerc, Comte de Buffon, later questioned ...

Snakes are elongated, limbless reptiles of the suborder Serpentes (/ sɜːrˈpɛntiːz /). [2] Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads ...
Pterodactylus (from Ancient Greek: πτεροδάκτυλος, romanized: pterodáktylos ' winged finger ' [2]) is a genus of extinct pterosaurs.It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered.
Spinosauridae (or spinosaurids) is a clade or family of tetanuran theropod dinosaurs comprising ten to seventeen known genera. Spinosaurid fossils have been recovered worldwide, including Africa, Europe, South America and Asia. Their remains have generally been attributed to the Early to Mid Cretaceous. Spinosaurids were large bipedal carnivores.
