Titanosaur

Yesterday, the American Museum of Natural History opened the biggest dinosaur exhibit in its history, or at least the largest exhibit of any single dinosaur. The museum is showing the largest Titanosaur ever discovered. The bones were found in 2022 and the species is new enough that we don't even have a formal name for it all the same. Like the previous record-holder, Argentinosaurus, the every bit-all the same-unnamed 122-human foot Titanosaur was constitute in Argentina. A visual comparison of how various Titanosaurs compare to a human being is below:

Titanosaurs, as the name suggests, are some of the very largest and heaviest dinosaurs to e'er walk the Earth. They were sauropods, a type of dinosaur characterized by long necks, relatively small heads, and four thick legs that are more than reminiscent of Grecian pillars than ordinary bones. The femur of this particular Titanosaur, for example, measured more than than eight feet long. This particular specimen was an estimated 121 anxiety long and weighed in at 70 brusque tons (63 metric tons). That'southward big, even by dinosaur standards, only scientists have adamant that this dinosaur was but a juvenile.

This particular sauropod had pointier teeth than you lot might look on a herbivore, according to Ars Technica, and scientists think it likely fed like a huge lawn mower — take a pace, sweep the area in front of you for plant matter, swallow (without chewing), stride, and sweep forward once more. Ane of the misconceptions about sauropods in full general is that they held their heads high, but their necks wouldn't have been flexible enough to permit it in animals of this size. Titanosaurs are idea to have lived in herds for mutual defense and protection. The sheer size of a Titanosaur would have been its own defense — even Tyrannosaurus Rex, one of the largest predator dinosaurs (at least on land), would've weighed a fraction of a full-grown Titanosaur.

The new Titanosaur is thought to be ~ten% larger than the Titanosaur Argentinosaurus, which was discovered in 1991. We but have a partial skeleton of that dinosaur, but scientists have washed some interesting work on estimating how it walked and what its gait looked like. A 2022 digital reconstruction of the creature based on a musculoskeletal analysis (the first ever performed on this type of dinosaur) produced a video that makes the massive beast look nearly dainty.

The maximum speed of Argentinosaurus was 5mph according to the reconstruction — groovy for a creature thought to weigh eighty tons (73 short tons). These sauropods are idea to have survived upward to the Cretaceous–Paleogene extinction consequence, only were wiped out, along with the other non-avian dinosaurs, when the shooting star hit.
