for freshwater crocodiles(they like to live near to lakes, rivers., etc..,) and for salt-water crocodiles(they live in sea water and some salty lakes..)..

There are a number of things that the prehistoric man did. Fishing, hunting and gathering were the main activities they engaged in.

Animals such as PROCOPTODON,DIPROTODON,TOXODON,MAMMUTHUS,DEINOTHERIUM,COELODONTA lived in the quaternary period.Plants such as BIRCH,SWEETGUM lived in the quaternary period, as well as the plants and animals you see around you.

This ancient species probably ate aquatic vegetation it scraped from swamps or lakes with its shovel like tusks.

Mammoths evolved 5 million years ago, during the end of the Neogene Period. They died out during the Quaternary Period, starting 10,000 years ago, with a few dwarf types surviving until 4,500 years ago.

The pets cavemen had are either unknown or extinct. What I have heard is that those pets were NOT dinosaurs, because dinosaurs were living billions of years before there was anything even remotely similar to a human.

The definition of 'pre-historic' assumes that the period was before written records. Obviously easily satisfied for the fossil collectors.

Archaeology concerns itself with the early history of mankind (and other life forms) and attention is usually paid to settlement regions, middens and waste sites, early tool forms and so on. So a knowledge of the food species (botany and zoology) and some knowledge of tool working techniques. e.g. How did they make that ochre paint for the walls.

Recent work in the Pacific in studying the common root of (non-written) languages has helped identify the migration patterns throughout that region.

A whale's song travels faster than a bird's chirp. This is because a whale's song travels through water, where sound moves much faster than it does in air.

Well, it started back awhile ago. When the people that sailed the water did not want people to trade over the sea, they told settlers to not go near the water, for fear of being eaten by something or the big waters that tip and sink ships. Because of this, hardly anyone wanted to fish out into open seas. So, the sharks actually had a chance to grow their full body length. But, now, since so many people around the world are fishing and trapping, the sharks don't have a chance to reach that maximum length. Although, more than 90% of our oceans are unexplored.

Animals in the ocean that lived in the Cenozoic period were sponges, coral, starfish, sea urchens, and sand dollars were common as well as brachiopods and cephalopods which were rare. Even oysters, mussels, and snails lived through out the period. Crabs and barnacles were common as well. On land, spiders, centipedes, scorpions, and insects, including butterflies, moths, bees, wasps, ants, beetles, and many others thrived during the Cenozoic era as well.

Answer

No one can say with absolute certainty what color the megalodon was. It is assumed that it followed the same pattern as all comparable animals, with a darker back and a paler belly.

Answer

For hunting adaptations. When prey is above the Megalodon, its darkish blue color blends in with the depths and colors of the ocean. When prey is under the Megalodon, the white underbelly blends in the the bright top of the water, where the sun shines down.

Well as the ice age ended it got warmer which is one factor and also just like many other extinct animals they were hunted by cavemen in various way's such as dropping large boulders onto them when they lure them into to tight gaps.

Elephants are less hairy than mammoths and do not posses such large tusks.

Elephants are not extinct, while mammoths are.

No. The saber-toothed cats evolved 22 million years ago.

4,000 years ago

New DNA research shows the world got too wet for the giant animals to survive.

Summary: Humans did not cause woolly mammoths to go extinct climate change did. For five million years, woolly mammoths roamed the earth until they vanished for good nearly 4,000 years ago and scientists have finally proved why.

They used kinetic energy. They would find witty ways to transfer small amounts of energy to to getter amounts with things like wedges, pulley systems, springs, etc.

Trilobites originated during the Cambrian era, flourished through the Paleozoic era, declined during the Devonian era, and finally became extinct in the Permean mass extinction event.

In total there were live trilobites on the earth for about 290 million years.

The last common ancestor of all animals was likely an organism not unlike modern-day protists.

A single celled animal, not a plant found in the deepest oceans.

Yeah, it's irrigation ditches...thanx

I believe saber tooth cats had such short tails because evolution didn't find the perfect design yet. Today's wild cats are evolution's finished product of the saber tooth tiger.

The current era of the Earth, the Cenozoic, is the Age of Mammals, in which they occupy most ecological niches for higher animals. The preceding era, the Mesozoic, is called the Age of Reptiles (66 million to 252 million years ago).

The saber tooth tiger is usually about 4 to 5 feet long and 3 feet tall. It weighed about 440 lbs which is about 200 kg.

Mammoths eat Meet Like Back then they ate Dear or Jaguars They are Carnivores

Dire wolf remains have been found across a broad range of habitats including the plains, grasslands, and some forested mountain areas of North America, and in the arid savannah of South America.
