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 ...
Komodo dragons, the world’s largest species of lizard, have iron-tipped teeth that help them to rip their prey apart, according to new research. Komodo dragons, the world’s largest species of ...
This group of lizards includes some more popularly known, such as the domesticated bearded dragon, Chinese water dragon, and Uromastyx species. One of the key distinguishing features of the agamids is their teeth, which are borne on the outer rim of their mouths ( acrodonts ), rather than on the inner side of their jaws ( pleurodonts ).
Heterodontosaurids were fox-sized dinosaurs less than 2 metres (6.6 feet) in length, including a long tail. They are known mainly for their characteristic teeth, including enlarged canine-like tusks and cheek teeth adapted for chewing, analogous to those of Cretaceous hadrosaurids. Their diet was herbivorous or possibly omnivorous.
A new study suggests Tyrannosaurus rex had giant, full gums and lips that covered much of their teeth.
Trachodon (meaning "rough tooth") is a dubious genus of hadrosaurid dinosaur based on teeth from the Campanian-age Upper Cretaceous Judith River Formation of Montana, U.S. [1] It is a historically important genus with a convoluted taxonomy that has been all but abandoned by modern dinosaur paleontologists.
In 2007, Peter Galton, reviewing the archosaurian fossils of the 1834 Bristol finds, reaffirmed the identification of the two teeth and humeri of Palaeosaurus platyodon (Rileya) as belonging to a phytosaur, and regarded P. cylindrodon (Palaeosauriscus) as an indeterminate archosaur.
In prehistoric Oklahoma, Astrodon lived alongside other dinosaurs, such as the sauropod Sauroposeidon proteles, the dromaeosaurid Deinonychus antirrhopus and the carnosaur Acrocanthosaurus atokensis. [20] [21] The most common dinosaur in the paleoenvironment preserved in the Antlers Formation is the ornithopod Tenontosaurus.
