Is Amphicoelias bigger than Argentinosaurus?
Studying an animal secondhand is obviously not ideal, and Amphicoelias is usually excluded from the list of biggest dinosaurs based on lack of evidence. “Certainly the new animal appears to be at least as large as Argentinosaurus, and is a new species,” he said.
What is the difference between Spinosaurus and Spinosaurus Aegyptiacus?
Two species of Spinosaurus have been named: Spinosaurus aegyptiacus (meaning “Egyptian spine lizard”) and the disputed Spinosaurus maroccanus (meaning “Moroccan spine lizard”). Fragmentary additional remains from Bahariya, including vertebrae and hindlimb bones, were designated by Stromer as “Spinosaurus B” in 1934.

When did the Amphicoelias sauropod dinosaur live?
Amphicoelias (/ˌæmfɪˈsiːliəs/, meaning “biconcave”, from the Greek ἀμφί, amphi: “on both sides”, and κοῖλος, koilos: “hollow, concave”) is a genus of herbivorous sauropod dinosaur that lived approximately 150 million years ago during the Tithonian (Late Jurassic Period) of what is now Colorado, United States.
Why is Maraapunisaurus fragillimus only known from one bone?
Because Amphicoelias fragillimus (or, more correctly, Maraapunisaurus fragillimus) is known from only one bone, and no one knows where it is. The best option is to ignore this species and focus on the ones that can be properly studied.
Why was Amphicoelias fragillimus not recognized as a species?
Amphicoelias fragillimus isn’t recognized as a legitimate species of dinosaur by most paleontologists because it is only known from one single fossil vertebra and even that was incomplete. The vertebra was discovered in Colorado along with a bunch of other bones in the late 1870s and described by Edward Cope.
Why are amphicoelas so big compared to other sauropods?
So most paleontologists believe that Amphicoelas’ staggering measurements are the result of typos or exaggerations. Argentinosaurus, while hardly known from significant remains, is wonderfully present. We can go and measure them, get real numbers, double check one another’s work.
