Dinosaurs

Currently, it is not possible to bring dinosaurs back to life because all dinosaurs went extinct millions of years ago. However, scientists are working on genetic engineering and cloning technology that might one day allow us to create animals with dinosaur-like traits.

One of the primary Darwinian ideas for the extinction of dinosaurs is natural selection. This suggests that environmental changes, possibly due to a catastrophic event like an asteroid impact or volcanic eruptions, led to the extinction of dinosaurs as their traits were no longer advantageous for survival. Another idea is that competition with other species or inability to adapt quickly to changing conditions may have played a role in their extinction.

The youngest fossils are typically found in recent sedimentary rock formations or on the surface of the Earth. These fossils are often from organisms that lived within the past few thousand years, such as the bones of mammoths or ancient human remains.

The Jurassic is the second of the three periods of the Mesozoic. It was named for the Jura Mountains, where many of its fossils have been found.

+ "they became fossils because the bones turned into stone leaving them so we could find"

Fossilisation occurs only when creatures are rapidly buried. In the case of fossils they are found in sedimentary rock all over the surface of the Earth. This type of rock is formed by water where particles are broken down, sorted and deposited by the water. Most fossils (95%) are marine creatures such as shells and fish, with less than 1% being land creatures such as dinosaurs. Many fish fossils are found with skin in tact and some even found eating/swallowing other fish at the time they were rapidly buried. Dinosaurs are only found as fossilised bones. The skin etc is missing because during flooding the body has begun to decompose and when buried (fossilised) the bones were the only preseravable part remaining. Most fossils are marine creatures because during flooding, creatures closest to the sea bed will be buried first, whereas creatures higher up from the sea bed (land animals) are less likely to be buried in sediment and will instead decompose on the surface of the water.

See Pierre Julien and Guy Berthault sedimentation experiments 1986.

In descending order: Bruhathkayosaurus 144 ft

Seismosaurus 140 ft

Supersaurus 131 ft

Argentinasaurus 115 ft

Paralititan 114 ft

Argyrosaurus 98 ft

Diplodocus 92 ft

The problem is that the biggest one we have full skeletal remains is the Diplodocus, all the rest are guestimates based of a few bones and in the case of the Bruhathkayosaurus only one bone - the femur. If true, the Bruhathkayosaurus at an estimated 220 tons would edge out the Blue Whale as being the largest creature ever to have inhabited the earth.

There is a lot paleontologists can learn from dinosaur footprints.

The most obvious is that they can tell where particular genera & species of dinosaurs lived.

If you know which dinosaur made the tracks you can use an equation based on it's leg length to work out how fast it was travelling. From this you can infer what type metabolism the animal had. Did it have a high metabolism like modern day warm blooded birds and mammals or a a slow metabolism like modern day cold blooded reptiles?

You can also infer something of dinosaur social nature. Were they solitary animals like tigers or live in small prides like lions or huge herds like zebra?

You can also work out something of the health of the dinosaur in question. Was it injured and walking with a limp? In some instances, did it have injuries that did not hamper its day to day life? For example did it loose a toe or claw in the past but able to survive and return to normal health?

Some very rare fossil tracks can tell you of the hunting technique of dinosaurs. Was a carnivorous dinosaur following a herbivorous dinosaur?

no

No there's one called dave who lives under your bed. Make sure to give him a wet apple every 3 hours before he gets cranky.

Kronosaurus lived in warm shallow seas. Its fossils have been found in Columbia, South America, and Australia. They lived between 125 and 99 million years ago.

nothing they are too big

Stars Fell on Alabama refers to the Leonid meteor shower that was observed in Alabama on November 12-13, 1833. Thousands of luminous bodies shot across the sky in every direction and put on such a show that it is still referred to in songs and on the state license plates.

All animals that live today, or maybe more because people made some extinct

Dinosaur Planet for N64 never made it to the market, it was cancelled.

There is no evidence against the former existence of dinosaurs. On the contrary, there are numerous fossilized bones from over a thousand dinosaur species proving that they did exist.

Archaeopteryx fossils have been found in the Solnhofen Limestone of Bavaria, Germany. These fossils date back to the late Jurassic period, around 150 million years ago, and provide important insights into the evolution of birds from theropod dinosaurs.

An acanthostega has about 8 fingers and 6-7 toes.

The Pteradactylus (pronounced tare a DACT il) was a genus of small pterosaurs that ate fish and other small prey. Their fossils have been found in Africa and Europe, and are about 150 million years old.

The term "pteradactyl" is often used as a synonym of pterosaur. Pterosaurs are an extinct order flying reptiles whose fossils have been found on every continent except Antarctica.
