The Stone Age Caveman Diet

Cave Dwellers, The Demise of the Dinosaur What was outdoor life like for prehistoric man?

There was a time when dinosaurs walked our Earth, inhabited our swamplands, and were undoubtedly King of Beast. How do we know they existed? How did they disappear?

According to scientists, dinosaurs inhabited all of earth except the extremely cold areas, and could be found in numerous varieties of species, in different shapes, different sizes – some with scales, some with bony spikes, others with ferocious dagger-like teeth.

The tracks of these prehistoric giants can be found where they tramped across mud flats, which then hardened to stone, preserving their tracks. These impressions from the past mark their indisputable existence on Earth.

The largest known deposit of fossilized dinosaur bones in the world can be found in the Dinosaur National Monument, on the Colorado-Utah border. Dinosaur fossils have also been yielded in the tar pits of Rancho La Brea, in Los Angeles, and in the Atlantosaurus beds of Wyoming. In 1953, Tritylodon skeletons (a mammal-like reptile) were found 'weathering out' of the sandstone rocks near Kayenta, Arizona.

If animals have the ability to adapt to changes in their environment, why have some died out completely? Why could a species exist for years upon years, then swiftly vanish? Just where did the dinosaur go?

Scientists offer many theories relevant to the disappearance of dinosaurs. The problem with theories is - they are theories. There is no bona fide documentation of prehistoric animals. No one that the present world knows of, ever interviewed a caveman, or anyone who came in contact with a dinosaur. Yet, we know they existed due to the remnants of history; fossils, imbedded tracks, impressions from the prehistoric past.

Here are a few theories that have been offered to account for the demise of the dinosaur:

When flowering plants appeared on earth, they increased the amount of oxygen in the air, therefore causing dinosaur's breathing rates and heartbeats to increase to the extent that they burned themselves out.

Dinosaurs were poisoned by plants they ate.

They began to die off after Earth's continents, which had originally been a single landmass, broke apart, causing tremendous environmental changes, submerging huge areas, and radically altering the climate, a climate that the dinosaur could no longer survive in.

A giant meteor struck the Earth, then exploded and its debris filled the atmosphere for many years, darkening the skies and blocking out sunlight. As a result, the temperature was lowered, causing the extinction.

Another theory is that the flood described in the Bible contributed to the extinction.

Even now men speculate of the dinosaur's existence, its appearance and habitat. Movies spin wondrous tales around these unforgotten, vaguely charted prehistoric beasts. It is interesting to know that the latest of all fossil remains are those of early humans…..
