The main difference between brachiosauruses and brontosauruses is their size. Although both are incredibly large dinosaurs in their own rights, the former is longer, while brachiosaurus was generally taller. Brontosauruses weighed up to 33,000 pounds and reached a maximum of 28 feet in height.
Apatosaurus may be one of the best-known sauropod species, though it’s just as likely you first heard about this late Jurassic giant under another name: Brontosaurus. Why the two names? While examining sauropod fossils in the late 19th century, Yale paleontologist O.C. Marsh used two different terms to describe what he believed to be the ...
"Generally, Brontosaurus can be distinguished from Apatosaurus most easily by its neck, which is higher and less wide," says lead study author Emanuel Tschopp, a vertebrate paleontologist...
As was the case with Diplodocus and Brachiosaurus, early paleontologists tentatively proposed that Apatosaurus spent most of its time underwater, holding its neck out of the surface like a gigantic snorkel (and perhaps looking a bit like the Loch Ness Monster). It's still possible, though, that Apatosaurus mated in the water, the natural ...
Apatosaurus was a sauropod of spectacular proportions. But there's a debate raging for decades about whether its genus should cancel out the Brontosaurus.
Apatosaurus and Brachiosaurus are both large, long-necked dinosaurs that lived during the Late Jurassic period. However, there are some key differences between the two. Apatosaurus, also known as Brontosaurus, had a more horizontal posture with a long neck and a long, whip-like tail.
Brachiosaurus and Brontosaurus are both giant, herbivorous dinosaurs that lived during the Late Jurassic period. However, there are some notable differences between the two. Brachiosaurus was known for its long neck and front legs, which were longer than its hind legs, giving it a unique posture.
The scientists ultimately showed that Brontosaurus was distinct from Apatosaurus, one of the main differences being that Apatosaurus was more massive and robust with a thicker and lower-set neck than Brontosaurus.
Brontosaurus and Apatosaurus are closely related, but show distinct differences in the morphology of their neck bones; Brontosaurus exhibits a wider neck than Apatosaurus. Additionally, there are variations in their bone structures, with the Brontosaurus having a more robust build.
The name given to the first specimen of the species to be discovered, Apatosaurus, became the accepted scientific name; Brontosaurus became invalid, or, at best, considered a redundancy—even though for most people, Brontosaurus remained the best-known name for the popular dinosaur.
