Its bones was first discovered by John Estaugh Hopkins as he was digging a pit in New Jersey in Later in , William Parker Foulke was on vacation in the area and noticed the bones.
He then decided to excavate them. Foulke called in paleontologist Joseph Leidy and the two then began to study the bones together. Only one skeleton of this dinosaur has been found, and it shows just how big it was. Q: Are there misconceptions about Hydrosaurus weberi that you would like to correct among those who have heard of it but who do not know it well?
Just invest in their cage, lighting, supplements, and other needs; they can be very beautiful to keep. Q: For someone who is interested in keeping a Hydrosaurus weberi for a pet, can you give them things to consider before taking the plunge? Who would they make ideal pets for? Or are they better suited to aficionados who want to study them?
A: They need a big space, money to invest in a nice UVB, enclosure, supplements and other caging needs. They need time and proper husbandry and understanding of this animal. We should understand our reptiles rather than the reptile understanding us. For me it is more for the serious reptile keeper.
Q: How much of a commitment does it take to keep Hydrosaurus weberi, and what advice would you have for someone who is keeping them for the first time? Were there any mistakes that you made as a beginner that you feel other beginners should learn from? A: As a beginner with Hydros, which was like 10 years ago, I was told that they feed mainly on veggies and that they are iguanas. Thus the growth was bad and slow. Full Site.
Physical Sciences. Subscribe to the newsletter. News Staff. Microscopic analysis of scratches on dinosaur teeth may have helped scientists unravel an ancient riddle of what a major group of dinosaurs - the Hadrosaurs - ate and exactly how they did it.
A study led by the University of Leicester has found evidence that the duck-billed dinosaurs called Hadrosaurs had a unique way of eating, unlike any living creature today. Working with researchers from the Natural History Museum, the study used a new approach to analyze the feeding mechanisms of dinosaurs and understand their place in the ecosystems of tens of millions of years ago.
Palaeontologist Mark Purnell of the University of Leicester Department of Geology, who led the research, said, "For millions of years, until their extinction at the end of the Cretaceous, duck-billed dinosaurs — or hadrosaurs - were the World's dominant herbivores.
They must have been able to break down their food somehow, but without the complex jaw joint of mammals they would not have been able to chew in the same way, and it is difficult to work out how they ate. It is also unclear what they ate: they might have been grazers, cropping vegetation close to the ground - like today's cows and sheep - or browsers, eating leaves and twigs - more like deer or giraffes.
Not knowing the answers to these questions makes it difficult to understand Late Cretaceous ecosystems and how they were affected during the major extinction event 65 million years ago.
