Apart from Tyrannosaurus Rex and Triceratops, dinosaurs with long necks are easily recognisable as prehistoric animals. Whenever someone says the word dinosaur, it’s one of the most likely images you’ll think of. They are quite prevalent in movies, toys, and various forms of merchandise and pop-culture.
For a long time, scientists have been researching whether or not dinosaurs were feathered. Getting evidence of feathered dinosaurs is nearly impossible. Because feathers are of keratin. They tend to break down before it becomes a fossil. But, still, some facts show the existence of feathered dinosaurs.
Dinosaurs were hatched as new offspring from eggs laid by female dinosaurs. Their eggs were identified and described for the first time in 1859. These eggs were elongated or round and had brittle shells. Other than oval and elongated some potato-shaped, football-shaped, grapefruit-sized eggs have also been observed. There have been different egg placements such as in the groups of 5-25, in the circle-shaped, and spiral-shaped arrangement. While some dinosaurs also laid eggs in rows.
It is a story that dates back to the times of a great naturalist called Charles Darwin and even before him. Before him, organisms were being classified into kingdoms and lower taxa, but the basis for their classification was mainly focused on morphology.
