The teeth of the dentary were much smaller than those of the maxilla. The third or fourth tooth in the dentary of Dilophosaurus and some coelophysoids was the largest there, and seems to have fit into the subnarial gap of the upper jaw. Most of the teeth had serrations on the front and back edges, which were offset by vertical grooves, and were ...
[48]: 232–233 Teeth are continuously replaced during life. Teeth that are erupted and currently in use are termed the functional teeth. For each tooth position, there are typically one or two unerupted replacement teeth at any time, which successively migrate into the tooth socket and replace the functional tooth once the latter fell out ...

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."
Some of the most important anatomical information about dinosaur teeth is collected from polished, microscopically thin sections , including the types of dental tissues present, tooth wear, tooth replacement patterns, how the teeth are attached, and the frequency of replacement. The actual material comprising a dinosaur tooth is not very ...
This is a list of non-avian dinosaurs whose remains have been recovered in Africa.Africa has a rich fossil record. It is rich in Triassic and Early Jurassic dinosaurs. . African dinosaurs from these time periods include Megapnosaurus, Dracovenator, Melanorosaurus, Massospondylus, Euskelosaurus, Heterodontosaurus, Abrictosaurus, and Lesoth
Tetanurae (/ˌtɛtəˈnjuːriː/ or "stiff tails") is a clade that includes most theropod dinosaurs, including megalosauroids, allosauroids, and coelurosaurs (which includes tyrannosauroids, ornithomimosaurs, compsognathids and maniraptorans, the latter including living birds). [1]
