Prehistoric Animals

Parent Category: Animal Life
Prehistoric animals represent the vast majority of extinct animals. Through exploration, scientists are piecing together from the first sea dwelling organisms to modern day species. Types of questions covered are about animals who existed before recorded history and the ever popular debate as to what caused the dinosaur extinction.
Slight shifts caused frequent ice ages. Polar ice advanced and  retreated each time, carving and moulding the land. A pattern of  the Ice Ages emerged, but by the last Ice Age, the ice began to  melt and the sea levels rose rapidly. Many ice land bridges were  formed between continents.  There...
Unknown. No one knows how long any dinosaur eggs took to hatch.
Actions have reached $1500. That's all I know.
By fossilisation and permineralisation.  Fossilisation is caused by layers upon layers of sediment  burying the bones. As the layers of sediment above the buried bones  increases, so does the pressure on the layers of sediment lower  down. The pressure becomes so great that the bones and the ...
A recent megalodon tooth was found off the coast of hawaii and it  weighed in at 2 lbs based on all megalodon tooth findings the  average is about 1.5 lbs
Well it did produce meat for carnivores
The fat or blubber of an animal was rendered into oil.
Mean surface temperature over period duration 16.5 °C is the  closest I could find. 
Dinosaurs were once considered reptiles, but now they are thought to be a separate group of their own closely related to reptiles and birds.
the tree died about 65 million years ago along with many other  species of dinosaurs. They died by an asteroid in most scientific  theories including mine, and I'm a science teacher
There were many sub species of T rex such as the bronchi, the  scroter, and the ankli. But the main T rex which dominated the  Jurrasic period and all of east Africa, Central Europe and Southern  South America was the astounding Tyranni Rexamo
Yes, in 1971. The human found has been dubbed "Malachite Man", but  many argue that he had been buried in a collapsed mine.
like many other extinct animals/ things that were at the  dinosaur age  either died because a huge volcanic explosion or an asteroid hit  them all 
Technically all of them. Genes are found in almost every cell'snucleus and are made from strands of DNA (deoxyribonucleic acid). Amosquito drinks your blood which is made of red and white bloodcells.
Pterodactyls were animals and thus consumers.
Well one thing you need to remember, most prehistoric animal have adapted and evolved into more useful and dominant forms. While I'm sure no one believes that humans evolve from apes anymore, it is possible for animals to evolve and adapt to their needs. For example: some of the smaller reptiles...
Fossils of dinosaurs and mammals have been found in the same strata. Mammal bones have been found in the stomachs of some predatory dinosaurs.
No. There were many type of sabre-toothed cats however.
First, it had really long claws to be able to kill its prey fairly  quickly.   Second, it was very fast, so it could sneak up and kill its prey  even if the prey tried to run away.   And third, it could jump fairly high so when it climbed on its  prey, it would be able to get it easier.  ...
Paleontologists can never be sure because we have not observed these magnificent beasts ourselves but most likely yes because of its small size it would not be able to hunt large herbivores itself so it was forced to eat babies but that is not suppliant considering animal parent protection and...
Type your answer here... A t rex was alive for 3,227
I think that it is USA. It is quite big and there have been man  discoveries there.
There are several large craters in the earth and one of them may  have killed them off.
Teeth, fore and back claws, physical body, tail armour, body armour  and horns.
The saber tooth tiger has many remains depending on the species, Smiledontnas Nimbradious is found in the foothills of eastren oregon. Smiledoont and the larger cats are found in the La briear tar pits of Los Angleous calefornia, and the wendell fossil beds in siberia.
Animals that lived during the prehistoric period are called prehistoric animals
they have found fossils of sabers all around the world.
scientists really don't know how to answer that question yet, but  most people say it got killed by a meteorite, then so be it.
The length of their canines varied between species, but the longest  they could get is up to 20 inches.
No the ankylosaurus was about 10 feet tall and 20 feet long
Andrewsarchus, Baluchitherium (Indricotherium), Cave Lion,  Chalicotherium , Coelodonta (woolly rhino), Dinictis, Dinohyus,  Doedicurus, Elasmotherium, Glyptodon, Indricotherium, Mammoth,  Mastodon, Megatherium, and Saber-toothed cats. 
Certainly the most famous dinosaur is the t-rex, but there were  many other larger dinosaurs. The biggest carnivore is spinosaurus.  The smallest is Microraptor. Deinonychus was well known for its  unique upright claw, and Triceratops has an  impressive set of horns. The Parasaurolophus could...
From the trassic period to the cretaceous period (about 225 years  ago to 65 years ago)
Yes they hunt and live in a pack
how was the reaper helpful to farmers 
we live in the common era c.e
  Look for a claw in the top right corner
they leave there eggs behind they dont care for they have to grow up on there own with no support or protection.
The tyrannosaurus Rex was about 20 feet tall, the height of a two story building, when stretching to full height. In a normal walking posture, a tyrannosaurus Rex would walk horizontally to the ground, unlike a human, which would cause it to be about 12 feet at the shoulder, a little higher at the...

Triceratops are preys
The tyrannosaurus rex is a predator feeding on anything it could fit in its mouth
the triceratops guarded its babies by charging at predators and  stomping its foot much like how a bull does when its going to  charge
Most likely the plant eaters died first, then the carnivores.
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.
yes, it had lots of hair, pretty warm in da snow
The only animals that would have chased mammoths would have been their predators. A wide variety of animals, including Dire wolves, flat faced bears, cave hyenas, American and European lions, and saber toothed cats would easily kill and eat an unprotected mammoth calf. The only animals that could...
Stromatolites are formed through the trapping of sediments and the precipitation of calcium carbonate in response to the growth and metabolic activities of matlike cyanobacteria colonies. Due to the matlike growth of the cyanobacteria, laminar sedimentary structures are formed.
It looks like a Draciasourus but it a little bit smaller and it has  a thin tail at the end and when it is threatened it can swing its  tail around and make a whip sound and scare its predators
The Late Triassic epoch was a part of the Triassic period of the  Mesozoic era. It was divided into, in chronological order, the  Carnian, Norian, and Rhaetian ages.
All dinosaurs were different shapes and sizes. Try to be a bit morespecific.
Great model in NY's museum of natural history.
Good question. Not many people know the answer to that one, but I believe the current theory is that oxygen levels were higher. Nobody knows for sure, though.
Saber Toothed Tigers were endangered but they are extinct now.
Saber Toothed Tigers were endangered but they are extinct now.
You can compare it to a water buffalo because a male water  buffalo can weight up to 2 tons 
it is very likely because they are very closely related to birds and birds do sing to there offspring.
because he knew his enemy was were his tail was
Wide enough to swallow an average 4th grader.
The average size for dinosaurs is about the size of a sheep. Most dinosaurs were not the size of T-rex and Triceratops.
The pterandon was a flying reptile and not a dinosaur as many  people believe. It is believed that they died out and became  extinct due to a direct meteor hit to the Earth.
Mammoths eat Meet Like Back then they ate Dear or Jaguars They are Carnivores
It was carnivorous, meaning it ate meat. Its diet probably  consisted of smaller dinosaurs that lived around the same area and  time as it did.
It was a bunch of ferns and really tall trees
Yes they are hollow like a birds bones. which indicates that a  dinosaur was more bird than reptile after all but some had bones  that were not hollow.
Yes. Dinosaurs and pterosaurs were both archosaurs, a branch that also include crocodilians.
Yes. All dinosaurs had amniotic eggs.
Predator but prey to the woolly mammoth.

Pterosaur is the modern and proper name for "pterodactyl."
Allosaurus is no where near being as large as a tyrannosaurus Rex.  tyrannosaurus Rex is 40 feet long and the Allosaurus is only 35  feet long
Perhaps you can't, but carbon dating is not used on mineralized fossils. The igneous rock above and below the fossil strata is radiometricly dated, Carbon dating is only good on material containing carbon; material less than 40,000 years old.
Water is pretty much the same in all times and places. Jurassic water would have been somewhat purer than today's, thanks to human pollution, but not significantly better than water in North America before Columbus. As for microbes and plant matter, those would have been slightly different, but the...
