Brontosaurus (/ ˌ b r ɒ n t ə ˈ s ɔːr ə s /; [1] [2] meaning "thunder lizard" from the Greek words βροντή, brontē "thunder" and σαῦρος, sauros "lizard") is a genus of herbivorous sauropod dinosaur that lived in present-day United States during the Late Jurassic period.

2025年1月4日 · Brontosaurus, large herbivorous sauropod dinosaur living during the Late Jurassic and Early Cretaceous epochs (163.5 million to 100.5 million years ago). Recovered specimens measure roughly 20.3 meters (about 66.5 feet) long.

2023年9月25日 · The Brontosaurus had peg-like, straight, and thin teeth designed for raking and stripping vegetation. This reflects a homodont tooth pattern, where all the teeth are uniform in shape, rather than the varied types found in mammals.

2021年2月23日 · A key feature was to have short blunt teeth. This enabled them to pluck leaves and small branches from plants and grind them a little before swallowing them whole for digestion. A Brontosaurus would live as long as a giant tortoise.

2022年4月4日 · Brontosaurus was a large animal with distinctive features like long, wide and deep neck; and large whip-like tail. Its skull remains have never been found, but scientists believe that it was similar to the skull of the Apatosaurus. It had chisel-like teeth only on the front of their jaws. Their neck vertebrae were deeply bifurcated.

Like Apatosaurus, their skull could be also smaller in proportion to the body with a squared snout and spatulate (chisel-like) teeth in the jaws, adapted for eating plants and vegetation. Several estimates of Brontosaurus size have been made.

2012年4月10日 · The sections of upper and lower jaws were set with spoon-shaped teeth, and these are the skull portions which make up the head of the famous 1883 reconstruction of the dinosaur Marsh...

2024年1月25日 · Its skull was long, narrow, and equipped with small, peg-like teeth that were well-suited for stripping leaves from branches. This unique anatomical feature is a defining characteristic of the Brontosaurus and contributed to its distinct appearance among other dinosaurs of its time.

2025年1月19日 · Another difference between these two dinosaurs is their teeth; while Brontosaurus had teeth that were very flat in shape with no cutting edges, Apatosaurus had teeth that were more pointed at both ends with serrated edges along their length which would make it easier for them to break through hard plant material.
