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."
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
Life restoration showing hypothetical complete crest-shape, similar to that of the related Guanlong. Proceratosaurus possessed a nasal crest, which may have served as a display organ but also possibly served to reduce bending stresses on the skull when biting. This may indicate Proceratosaurus used a puncture-pull strategy for hunting prey.

Speculative size compared to a human. Dracovenator is estimated to have measured between 5.5 and 6.5 m (18 and 21 ft) in length and 250 kg (550 lb) in body mass. [2] [3] The holotype specimen, BP/1/5243, consists of both premaxillae, a fragment of the maxilla, two dentary fragments, a partial surangular bone, a partial angular bone, a partial prearticular bone, an articular bone, and several ...
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 ...
