An herbivorous dinosaur is a dinosaur that only eats plants. The majority of dinosaur species were herbivores, including the brachiosaurus, stegosaurs, triceratops, astrodon, ankylosaurus and ornithopsis.
It has been suggested that approximately 65 percent of dinosaur species were herbivores, where roughly 35 percent were carnivores, or theropods. Examples of well-known carnivorous dinosaurs are the tyrannosaurus rex, or T-rex, and velociraptor. A very small number of dinosaur species were omnivores, meaning they ate both plants and animals. Most herbivorous dinosaurs were actually omnivores in a sense, because they often accidentally ingested small animals and insects when eating plants.
In all animal populations, there tend to be more herbivores than carnivores. More plant eaters are needed at the bottom of the food chain in order to supply food and energy to carnivores at the top of the food chain.Learn More
Individuals who believe that they have found a fossilized dinosaur bone in an outdoor area should avoid touching it and instead take a photo and make note of its exact location using a map before making contact with a natural history museum such as the Smithsonian National Museum of Natural History in Washington, D.C. However, this procedure is not legally binding, particularly if the fossil is discovered on private land, though moral obligation may tell a different story. In the United States, individuals who find a fossil on their land are not required to report or hand it over to any authority.Full Answer >
Though there have been a few instances of scientists purporting to have found larger specimens, the longest known dinosaur that is widely accepted by paleontologists seems to be the Diplodocus, a type of sauropod dinosaur with a long neck and long tail that is said to have measured as much as 175 feet in length. There seems to be some controversy and debate around the question of which dinosaur is truly the longest, with scientists introducing competitors such as the Seismosaurus, which was once thought to be a distinct species but was eventually found to be a very large Diplodocus specimen. The Seismosaurus' discovery was announced in 1991, but its existence as a unique species was debunked just over a decade later, a fact that was announced at an academic event in 2004.Full Answer >
The fossilized remains of Sue the T. rex were found near Faith, S.D., during the summer of 1990. As of 2014, Sue is considered to be the largest and most complete skeleton of Tyrannosaurus rex ever found. Sue measures 40.5 feet and weighs over 3,900 pounds.Full Answer >
Velociraptors were about 1.6 feet tall at the hip and weighed up to 33 pounds, approximating the size of a turkey. They were significantly smaller than other members of the dromaeosaurid family, such as Deinonychus. Tail included, velociraptors could reach a length of 6.8 feet.Full Answer >
