What Inviorment Did the Spinosaurus live in?
Spinosaurus aegyptiacus lived in coastal mangrove swamps, eating fish.
What is your explanation of how and why dinosaurs became extinct?
Well the main theory is the asteroid theory. I agree that it was an asteroid as there is a lot of evidence for it. For example, there is a layer of iridium covering the earth which is found in asteroids. also there is a crater in Mexico called the Chixulub crater which is said to be from 65 million years ago at the time of the dinosaur's extinction. Also the impact of an asteroid hitting earth would have caused the earths atmosphere to be filled with dust, therefore blocking off the sun so photosynthesis wouldn't happen so plants would die, herbivores would die as there would be nothing for them to eat and the same for predators so there would be no dinosaurs left.
How did Jesus survive the dinosaurs?
By not seeing any dinosaurs - according to the theory of Evolution, he lived millions of years later. Of course, from the Creationist point of view, Jesus lived only thousands of years after the dinosaurs - by which time, the climatic changes brought about by the Flood had resulted in the extinction of most large land dinosaurs as we know it. Incidentally, documented sightings of dinosaurs and dragons right into the middle ages were not uncommon, so even if there were a few remnants still around, they remained hidden. Remember that Jesus had/has power over all creation, so he certainly could have commanded the dinosaurs, just as he commanded the wind and the waves and the laws of physics as we know them.
The Jurassic Period was the era known as the Golden Age of Reptiles.
Did the cretaceous or permian extinction cause dinosaurs to become extinct?
No, as there was no Cretaceous-Permian extinction. There was the Permian-Triassic extinction, which ocurred before the dinosaurs appeared. Non-avian dinosaurs were wiped out in the Cretaceous-Paleogene extinction.
Actually, the smallest known dinosaurs were even smaller than chickens. Epidexipteryx weighed only 0.36 lb, and was less than 10 inches long. You are probably referring to Compsognathus, which was actually somewhat larger than a chicken (the chicken sized estimate was based on a fossil of a juvenile before it was realized that the individual was not fully grown).
What is the fin on the dinosaur dimetrodon there for?
Dimetrodon was actually not a dinosaur; it was a prehistoric reptile that existed before the dinosaurs. The sail on their back was likely used for thermoregulation; it could be used to catch heat from the sun to warm the animal. It may have also been used as a display to communicate, make it appear larger, or attract mates.
What color was dinosaur blood?
All vertebrate animals have blood with hemoglobin, an compound that is used to carry oxygen in the blood. Hemoglobin is what gives blood a red color. Dinosaurs would have also had hemoglobin, and hence, red blood.
The Ichthyosaurus was a dolphin-like creature that was found in water. Differences between the dolphin today and the Ichthyosaurus would be a longer snout and smaller dorsal fin.
Can you have nitrogen atoms in your bodies that existed during the time of the dinosaurs?
Yes indeed. Nitrogen is a stable element and the amount present on Earth is endlessly recycled. While nitrogen atoms spend some time in rocks, in soil, in plant tissues and in animals (where they make muscles), eventually they return to the atmosphere whence they can be breathed in. Because atoms are so small, each human breath holds an astonishing number of them, and assuming that they're pretty well mixed, each breath you take holds - on average - three Nitrogen atoms from a dinosaur, and not just a random dinosaur, but a particular dinosaur. Of course, each of those atoms has spent some time in millions of dinosaurs.
Which small prehistoric flying animal got its name for Greek words meaning flying finger wing?
Pterodactyls or Pterosaurs were flying prehistoric lizards. Strictly, they were not dinosaurs.
Jurassic is one of the periods when dinosaurs lived. It is between the Cretaceous and Triassic periods. You can find out much more @ Wikipedia.
This is information gleaned from the website below
A reptile that lived between 220 million years ago and 65 million years ago, walked with its feet below it's hips, was maybe warm-blooded, had neither flippers or wings, and is closely related to modern birds. They just aren't oversized lizards.
Yes, because they are members of the phylogenetic clade Sauropsida ("lizard faces"). Note however that the term "reptile" is a paraphyletic (unnatural) assemblage of animals because it excludes the birds, which are also dinosaurs (since they descended from dinosaurs) and therefore reptiles.
How many kinds of dinosaur were there?
There are two options, people belive that if they multiply and divide right, they can find out how many were there, but then again, Scientists believe that the area where the most dinosaur bones and fossils found was at "East of Africa", scientists believe 9,000,935,985,784 dinosaurs were on the planet, so if that number was divided by the number the scientists had mathed out the answer would be about 400-600 types of dino's
Where does the apostrophe goin dinosaurs?
Dinosaur does not need an apostrophe. The plural form is dinosaurs. The singular possessive form is dinosaur's, as in "the dinosaur's tooth." Plural possessive would be dinosaurs', as in "the dinosaurs' eggs."
What are 2 biotic and abiotic factors that affected the Austrosaurus Mckillopi?
Like any land animal, two abiotic factors that would have affected Austrosaurus would have been air and water.
As for biotic factors, trees that supplied edible leaves would have been the most important biotic factor to Austrosaurus survival. If there were any predators, those would have been another biotic factor that would have effected them, as well as any other herbivorous dinosaurs that competed for the same food sources.

True or false - you are a dinosaur?
Dinosaur means terrible lizard. Since I am not big and terrible and I don't resemble a lizard I would say that I'm not a dinosaur. Will my progeny be different than I am and in a million years not resemble me, depending on the environment, I may become extinct.
