A: For that information on Spinosaurus, click here.
A: Apatosaurus' scientific name (its genus) is Apatosaurus. Dinosaurs are commonly known by their scientific name.
A: Saltopus was either a very early theropod (of an unknown family) or it may have been a lagosuchid (primitive reptiles that led to the dinosaurs) or an ornithosuchian (not dinosaurs, but closely-related archosauromorphs). Saltopus is only known from fragmentary remains and its classification is uncertain.
Insectivores (insect-eaters) are a type of carnivore (carnivores are organisms that eat other organisms). Saltopus was too small to be able to kill animals much larger than Mesozoic Era insects, but like many modern-day insectivores, it may also have eaten dead animals that it found.
A: No.
A: Protoceratops was an herbivore, a plant eater. It probably ate cycads and other prehistoric plants with its tough, hook-like beak. No one knows what color Protoceratops (or any other dinosaur) was. For more information on Protoceratops, click here.
A: 1. Bigger ones are being found all the time - I haven't heard of a theoretical limit being estimated (probably becasue it's likely to be proven wring by some new discovery).
2. Astrodon, Pleurocoelus, and Priconodon have been found in Maryland. For more dinosaur finds listed by location, click here.
A: No. Newly discovered dinosaurs are named by the discoverer or the paleontologist who determines that it represents a new genus. There are many different ways that dinosaurs are named. Sometimes the dinosaur is given a name that describes something unusual about it's body, head, or feet. Some are named after the location where they are found, their behavior, size, or in honor of a person. For more information on naming dinosaurs, click here.
A: It was a plant-eating dinosaur with many horns on its head. Click here for more information.
A: The Triassic period lasted from 248 - 206 million years ago. The late Triassic period was from 227-206 million yeasr ago. For more information on the Triassic period, click here.
A: For a page on raptors (dromaeosaurids), click here.
A: Click here.
A: Teratosaurus is a problem genus; the various species of Teratosaurus have turned out to be a variety of organisms, including dinosaurs and other reptiles. The type species, T. suevicus (von Meyer, 1861)is now caleld Pseudosuchia. As to the other species:
A: That is isn't known. Deinonychus nest and eggs have not been found, so it isn't known whether or not they cared for their young. For more information on Deinonychus, click here.
A: Pachyrhinosaurus is its real genus name. For information on Pachyrhinosaurus, click here.
A: Just about every feature on every animal is an adaptation. Some obvious ones are the animal's size, shape, skin color, how they eat, what they eat, and how they defend themselves (horns, armor, claws, etc.).
A: I don't know.
A: For information on Tanius, click here.
A: Pterodactylus went extinct towards the end of the Jurassic period - I don't know why.
A: No one knows how much any of the dinosaurs ate.
A: Styracosaurus weighed up to about 3 tons. For more information on Styracosaurus ,click here.
A: Look out your window. The Holocene epoch is the geologic time from about 11,000 years ago until now.
A: Yes -it was Brontosaurus (now called Apatosaurus). The original Brontosaurus fossil, found in 1879, lacked a skull (as many fossils do). Othniel Marsh added a skull found miles away (this skull did not belong to the Brontosaurus, but to a Camarasaurus). In 1900, Henry Osborn assembled another skull-less
Brontosaurus at the American Museum of Natural History in New York City, adding a cast of
Marsh's skull. In 1915, Earl Douglass of the Carnegie Museum found a Brontosaurus fossil that
included the skull, but because of Osborn's influence, the Carnegie displayed the fossil skull-less.
When Douglas died in 1932, the incorrect skull was put on display! It wasn't until 1975 that the
proper skull was mounted on Brontosaurus/Apatosaurus fossils in museums.
A: Dinosaurs bones often differ greatly in size and shape. It is pretty easy to tell the difference between some dinosaurs, like a giant one versus a small one, but sometimes it is very hars to know what dinosaur you've found.
For example, if you find a fossil whose bones are the same size and shape as those of T. rex, your fossil is probably a T. rex. Sometimes, however, it is difficult to determine which group (family, genus and species) a set of bones belongs to (or even if the set of bones belongs to a single type of dinosaur - sometimes many dinosaurs are jumbled together in a bonebed). If a new dinosaur is similar but not exactly the same as a known dinosaur, it is difficult to determine if the new dinosaur belongs to new group or if it belongs to the old group, but is perhaps different in age (maybe you found a young specimen of that dinosaur, which looks different than the adults) or gender (sometimes the males and females are quite different - sometimes they are similar in appearance).
A: About 1,000 dinosaur genera have been found so far, but many more existed. Each genus probably had many, many species. No one knows how many species there actually were.
A: Tyrannosaurus was a carnivore (that means a meat-eater). For more information on T. rex, click here.

A: Iguanodon was about 30 feet long (9.3 m), 16 feet tall (5 m), and may have weighed up to 5 tons. For more information on Iguanodon, click here.
A: For that information on T. rex, click here.
A: Almost everything we know about dinosaurs is from fossils, including their size, shape, how they moved, how fast they moved, diet, means of protection, where they lived, how smart they were, etc.
A: Click here.
A: See the faq's above.
A: The salary range is huge, depending on what you do as a paleontologist. Some paleontologists work for universities, some work at museums, some work for oil (or other) companies, some work for the government, some collect fossils, and some write books. Some paleontologists do many of these activities.
An example of a math problem in paleontology is determining the approximate weight of a dinosaur. You first have to make a model of the dinosaur, then determine its volume (by immersing the model into water and seeing how much water it displaces). Then you have to multiply by the scale of the dinosaur to find the actual volume (for example, if the model was 1/100 of the original dinosaur's size, you have to multiply by 100). Then you have to determine the dinosaur's density (by using the density of modern-day animals that you think would be similar in structure) and then multiply the density by the volume to find the approximate weight.
A: Gladiators entering the coliseim said, "Ave imperato morituri te salutant!" which means "Hail emperor, we who are about to to die salute you."
A: Click here.
A: During the Mesozoic Era (the time when the dinosaurs lived), the weather was mostly warmer than it is now. For those dinosaurs that lived at high latitudes (closer to the poles, having colder weather), migrating to warmer areas may have helped them survive the near-polar winter.

paleontologist Othniel C. Marsh in 1885. For more information on Camptosaurus, click here.
A: No
A: Fossils have been foud all over the world, but there are a few places that are very rich in fossils. They are called Lagerstatten. For more information on Lagerstatten, click here.
A: Dinosaurs probably lived in what is now Ohio, but no sedimentary rocks were deposited there during the Mesozoic Era, so there are no fossils. Instead of rock formation, there was rock erosion in Ohio during the Mesozoic (it was probably a relatively high area). This erosion would wash or crumble any dinosaur bones/fossils away. For more information, see "Fossils of Ohio," by Rodney M. Feldman, Ohio Geological Survey Bulletin 70, 1996.
A: Rex means king in Latin. Since T. rex was so big, "king" was thought appropriate.

A: Yes. The biggest volcano in our Solar System is Olympus Mons (it is 17 miles (27 km) tall and over 320 miles (520 km) across), located on Mars.
A: Carbon dating is not used on dinosaurs (or Pterodactly) fossils because it's half life is too short. The half-life of carbon-14 is 5,568 years. That means that half of the C-14 decays (into nitrogen-14) in 5,568 years. Half of the remaining C-14 decays in the next 5,568 years, etc. This is too short a half-life to date dinosaurs; C-14 dating is useful for dating items up to about 50,000 - 60,000 years ago (useful for dating organiams like Neanderthal man and ice age animals).
Uranium-235 (which has a half-life of over 700 million years) is used to date the lava layers surrounding dinosaur-era fossils. For more information on dating fossils, click here.

Q: what are some web sites with
the brontosaurs?
from mitchell D.,
Edson,
Alberta,
canada;
October 3, 2000
A: Brontosaurus is now called Apatosaurus. For a page on Apatosaurus dinosaur, click here.
A: False
A: Very little is known about the life span of dinosaurs. A few dinosaur fossils have been analyzed to determine their age at death (click here for more information). In general, the smaller the animal, the shorter the life span, so the shortest-lived dinosaurs would be the small ones (like Compsognathus).
A: Thank you! I don't know how they were hunted, but the hides, tusks and sinews (stringy, elastic tendons) were certainly used by people. The hides were used for clothing, bedding, etc. The tusks were probably used for a lot of things - a sturdy, pointed object often comes in handy. Some tusks were even carved as artwork. Sinews are strong, pliable strings, and can connect things, like a stick of wood and a stone, making a hammer. The bones may have also been used. For a mastodon printout, click here.
A: They mostly eat bamboo, which limits the range of pandas tremendously. Also, because of habitat destruction, the pandas now live in a series of broken ranges. For information on the panda, click here.
A: The biggest pterosaur (flying reptiles that were closely related to dinosaurs, but not actually dinosaurs) was Quetzalcoatlus. For more information on Quetzalcoatlus, click here.
A: No dinosaurs fit that description, but plesiosaurs, like Elasmosaurus, do. For more information on plesiosaurs, click here. For a page on Elasmosaurus, click here.
A: Lots of animals, like sea turtles, desert tortoises, gila monsters, horseshoes crabs, and many, many more. Some plesiosaurs, like Kronosaurus may have also.
A: Nigerosaurus (which means "Niger lizard") was found in the Sahara Desert, in the country of Niger.
A: The dinosaurs went extinct about 65 million years ago, at the end of the Mesozoic Era.
A: An anomalous amount of Iridium was found in some late Cretaceous deposits in Italy by Alvarez around 1979. This find led to the asteroid impact theory.
A: Blue-green algae
(also called cyanobacteria) can fix gaseous nitrogen using an enzyme called nitrogenase, which converts the nitrogen gas in air to ammonia. Many legumes get nitrogen from symbiotic, nitrogen-fixing Rhizobium bacteria the live in their root nodules. Actinomycete-nodulated angiosperms get nitrogen from symbiotic, nitrogen-fixing actinomycete fungi of the genus Frankia.
A: Click here for a page on dinosaur evolution.
A: Brachiosaurus was a huge, plant-eating dinosaur with a long, giraffe-like neck. For more information on Brachiosaurus, click here.
