Dinosaur Features: Some Observed Truth of Dinosaur’s early stage That Will Blow Your Mind.

Dinosaur features are relatively seen even in our daily domestic and wild animals as to how they start their journey of egg laying or having similar components such as mammals and to how they build their nests, how they live their lives and how they did survive through the periods during they existing period here on planet earth.

A few dinosaurs gave birth to live young, but most dinosaur laid eggs. The eggs and nests that have been found have much to tell us about how dinosaur lived. Like most reptiles today, dinosaurs had many young but did not usually look after them. Only a few seem to have nurtured their babies once they had hatched. There have been no egg finds for whole dinosaur families, such as the stegosaurus and ankylosaurus. But what we do know is very revealing. Communal egg sites tell us, that the dinosaurs who made them were sociable. Massive nesting sites tell us that like birds, some dinosaurs returned to the same spot every year to lay their eggs. Some egg nests were carefully constructed. They had leaf linings or earth rims. The eggs inside were often laid and arranged with care. But other eggs were laid as the dinosaur walked along, absent mindedly depositing her offspring in tracks behind her. Such act can also be seen in chameleons till this day.

Dinosaur Features: Inside The Egg.

Curled up snugly, an Orodromeus baby grows inside its egg. Eggs were often one of as many as nineteen, laid in a carefully arranged spiral, by a small, two lagged plat eater. Typical vertebrate eggs had a hard shell which let gases in and out. This would enable the growing dinosaur inside to take in oxygen. When the baby was ready to hatch, it was also ready for the outside world, ready to grasp what it being introduced to. Orodromeus hatchlings entered the world fully able to look after themselves. Their parents may have guarded the unhatched eggs; but would not have to look after the babies. We know this because nest finds shows eggs that have opened but remained untrampled. This shows that the baby left the nest immediately. Whether it discovered its new world in the relative safety of a small clutch of other baby orodromeus or struck out alone, this is still unknown.

Research findings have its records that a female Leaellynasaura stoops over her hungry hatchlings. As they chirp for food, she spits out a nourishing paste of half-digested plant food. The nests were hollowed in the ground and lined with insulating leaves. They generated the warmth as they decay and kept the eggs at a temperature necessary for the life within them to flourish. The babies would have been around 30 centimetres when they hatched and were totally dependent on their parents. Their bones were too weak to allow much movement, so they would have had to be fed in their nest.

We do now that some dinosaur babies were like this because nest finds have shown egg shells trampled into small pieces. One fins showed a nest full of babies. He instinct to stay mast has been very strong, because they all died there. Perhaps a parent was killed while foraging for food to bring back for them and the abandoned chicks’ starved to death.

Dinosaur Features: Feet And Footprints Of These Wonderful Creature

During their life on Earth dinosaurs evolved extremely effective ways of getting about. From the speedy two- legged meat eaters to the huge four- legged plant eaters, all of them walked on their toes. This did not necessarily make them as graceful, but it did mean that they could move their bodies with minimum effort and maximum efficiency. These feet also left the only evidence, aside from eggs and teeth marks, of what dinosaurs actually sis during their lifetimes. Dinosaur tracks were first found in 1896, but it took a while for science to realize the importance of this discovery, print could survive for the 656 million years or more since the dinosaurs became extinct. But survive they did and dinosaur footprint have much to tell us about their owners.

There are two different types of dinosaur feet. The bone structure of these two types gives a lot of information about how dinosaurs moved around.

The first foot belongs to a two legged or bipedal, therapod predator. The long, slender, birdlike toes gave a solid grip on the ground and kept the animal as well balanced as possible- all vital skills in the acrobatic twists and turns of a chase. Walking on toes also increased the length of the leg, so this dinosaur would have had a longer stride. This meant that it could walk or run faster. The second foot belongs to a four- legged or quadrupedal, sauropod plant eater. It had to hold and transport a huge amount of weight, and is remarkably similar to the foot of a modern day elephant. The toes were shorter and broader than in the theropod foot. Although the dinosaur walked on its toes, the hind foot was supported by a think, fibrous wedge which acted like the heel of a shoe. Like elephants do today, sauropods probably waked with their legs held stiffly. This wedge would have saved them the effort of having to lift the entire foot off the ground whenever they took a step, a great saving in an animal this size.

Dinosaur Features: Out For A Stroll.

In this scene, a group of Apatosauruses trek across the soft mud of a riverbank, one misty late Jurassic morning. Although they are difficult to read very accurately, the tracks dinosaurs left behind give us some clues about their appearances and habits. For example, the deep indentations left by these Apatosauruses give a strong impression of great weight. The sets of tracks are side by side, suggesting they were sociable, herd animals. Tracks left in mud flats sand dunes and swamps have now been found all over the world. Far more meat eater tracks have been discovered than plant eater tracks. This is almost certainly because meat eaters were much more active than plant eaters and probably spent much time patrolling their territory searching for pray.
