Is Seismosaurus a real dinosaur?
As announced at the annual GSA conference in 2004 (and detailed in print since that time), Seismosaurus was really an especially large Diplodocus, although paleontologists have (so far) retained its amended species name to designate the dinosaur as Diplodocus hallorum.
What did a Seismosaurus look like?
What did Seismosaurus look like? The Seismosaurus was an enormous large sauropod with a long neck and tail with a small head. They had huge, heavy-weighted bodies with short front legs. Their feet had five toes with a claw on one toe to defend themselves from predators.
Is Seismosaurus the biggest dinosaur?
At 120-150 feet Seismosaurus was the longest dinosaur. Diploducus, Supersaurus, Brachiosaurus, and its close relative Ultrasaurus approached lengths of 100 feet.
What prehistoric animals lived in Wisconsin?
Mammoths and Mastodons Like many other states in the central and western United States, late Pleistocene Wisconsin was home to thundering herds of Woolly Mammoths (Mammuthus primigenius) and American Mastodons (Mammut americanum), until these giant pachyderms were rendered extinct at the end of the last Ice Age.
When did Seismosaurus go extinct?
Seismosaurus became extinct at the end of the Cretaceous 65 million years ago, along with all the other dinosaurs and a myriad of other life forms, but they were on their way out long before.
Where was the Seismosaurus found?
The gigantic dinosaur skeleton that was originally named Seismosaurus was discovered in New Mexico in 1979. This skeleton is now considered by many paleontologists to represent one of the largest examples of the well-known sauropod Diplodocus, which has been found in Colorado, Wyoming, Utah, and Montana.
What did the Seismosaurus eat?
Seismosaurus was a quadruped, meaning that it stood and walked on all four legs. Its diet consisted of a wide variety of conifers, or evergreen trees, as well as other plants that included ginkgoes, cycads, horsetails, and ferns.
Why are there no dinosaur fossils in Wisconsin?
Evidence of dinosaurs in Wisconsin is limited, Frederickson explained, because of erosion and glaciers during the last Ice Age about 20,000 years ago that wiped away much of the fossil record.
What fossils have been found in Wisconsin?
Fossils of many groups of organisms have been found including stromatolites, conulariids, brachiopods, gastropods, monoplacophorans, trilobites, graptolites, and conodont elements. Wisconsin’s Cambrian rocks have also produced fossils of more aglaspidid species (around 12) than those of any other state.
Where was Seismosaurus found?
What is a seismosaurus?
Seismosaurus is a dinosaur that lived about 145-156 million years ago—during the Jurassic Period—in parts of Southern North America. It was initially discovered in the northern part of New Mexico by a group of hikers in 1979.
Did Seismosaurus travel in herds?
Seismosaurus lived about 150 million years ago during the late Jurassic period in what is now known as New Mexico in the United States. It is thought that Seismosaurus may have traveled together in herds and may have migrated when their food supplies became depleted though their only being the one holotype this isn’t known for sure.
Why did Seismosaurus have such a long agile neck?
It’s long agile neck would have been used to poke into the forests to reach foliage – Seismosaurus having the advantage of being able to reach high-growing foliage that the other large Sauropods wouldn’t have been able to reach, their large size and shorter necks preventing them from entering the forests and reaching the foliage.
Who discovered Seismosaurus Halli?
Its type fossil was discovered by a trio of hikers, in New Mexico in 1979, but it was only in 1985 that the paleontologist David Gillette embarked on a detailed study. In 1991, Gillette published a paper announcing Seismosaurus halli, which in a burst of reckless enthusiasm he said may have measured over 170 feet long from head to tail.
