Stegosaurus had a relatively low brain-to-body mass ratio.
“The technique uses the carbon 14 concentration in dental enamel and they get a date of birth,” scientist Bruce Buchholtz told WCBS 880’s Sophia Hall.
Stegosaurus would have lived alongside dinosaurs such as Apatosaurus, Diplodocus, Brachiosaurus, Allosaurus, and Ceratosaurus; the latter two may have been predators of it.
The remains of over 80 individual animals of this genus have been found.
Fossils of this genus date to the Late Jurassic period, where they are found in Kimmeridgian to early Tithonian aged strata, between 155 and 150 million years ago, in the western United States of America and Portugal. These were large, heavily built, herbivorous quadrupeds with rounded backs, short fore limbs, long hind limbs, and tails held high in the air.
Of the species that have been classified in the upper Morrison Formation of the western U. Due to their distinctive combination of broad, upright plates and tail tipped with spikes, Stegosaurus is one of the most recognizable kinds of dinosaur.
