It may have grown rapidly, attaining a growth rate of 30 to 35 kg (66 to 77 lb) per year early in life. The holotype specimen had multiple paleopathologies, including healed injuries and signs of a developmental anomaly. Dilophosaurus is known from the Kayenta Formation, and lived alongside dinosaurs such as Scutellosaurus and Sarahsaurus.
The "Cultural significance" section claims that the true head height of Dilophosaurus is about 3 meters (10 ft), but the diagram in the Description section, which depicts the largest specimen along with a smaller one next to a human figure, shows that the animal was no taller at the head than the average human (i.e. ~1.7-1.8 meters), which ...
Dilophosaurus skull reconstruction by Brian Engh; Dilophosaurus skeletal by Scott Hartman "A comprehensive anatomical and phylogenetic evaluation of Dilophosaurus wetherilli (Dinosauria, Theropoda) with descriptions of new specimens from the Kayenta Formation of northern Arizona."
One genus of the tangle web spiders has venom which is known to be medically significant. This genus, the widow spiders of genus Latrodectus, has caused human fatalities. The other genus, Steatoda, the false widow spiders, have bites that can cause pain and erythema but only around 30% of bites lead to systemic symptoms. [17]
The sylvatic cycle, also enzootic or sylvatic transmission cycle, is a portion of the natural transmission cycle of a pathogen. Sylvatic refers to the occurrence of a subject in or affecting wild animals. The sylvatic cycle is the fraction of the pathogen population's lifespan spent cycling between wild animals and vectors. Humans are usually ...
The Dilophosaurus scene was shot on a sound stage, and the animal's lower body was suspended from a catwalk with bungee cords. No CGI was used in creating the Dilophosaurus. [154] In both the novel and its film adaptation, a Dilophosaurus uses its venom on the character Dennis Nedry before killing him. [154]
Platypus venom is entirely different from other venomous creatures. While more research is needed, scientists believe it contains specific proteins that target the nervous system. Heptapeptide 1 ...
In addition to killing the prey, part of the function of a haemotoxic venom for some animals is to aid digestion. The venom breaks down protein in the region of the bite, making prey easier to digest. The process by which a haemotoxin causes death is much slower than that of a neurotoxin. Snakes which envenomate a prey animal may have to track ...
