into other more evolved beings, but the reality has been the opposite. Deposits of fossils such as the Burgess Shale (Canada), the Sirius Passet (Greenland), and the Chengjiang (China), are preserved types of “Burgess Shale.” This aquatic is

In the British lake, Loch Ness, some claim to have seen a giant creature, usually identified as a type of plesiosaur. However, if it really existed there could not be only one, right? There would be a group of them and they would be frequently seen when coming to the surface to breathe. Neither does it seem very logical for these creatures to live in water as cold as in the water in this lake. Being a reptile, requires the heat of the environment to remain active. It would be great to find one of them alive, but it seems that we will Thave be content with hese ato re the on ly pre formed bfossilized their many and well-preserved skeletons. historic y

There were herbivorous dinosaurs that had the shape of some animals that are not extinguished yet. Thanks to their fossilized footprints, today we know much about them.

Herbivorous Theropods

Imitators of Birds, Crests, and Claws Both the K Ornithomimidae and the Oviraptors must have had a similar structure to that of the large non-flying birds such as the ostrich, rhea, or the cassowary. One of the ornithomimids has taken its name precisely refering to one of these birds the ostrich (Struthio (Struthio camelus), camelus ), being denominated as the Struthiomimus Struthiomimus,, Some films have represented them ‘Ostrich Mimic.‘ The had and fleeing on grouped indins packs size of the bird andrints of all k otp ed by the formidable le fohad the run, pursued g d n o a p the dinosaur n ro a e d Th fingers antyrannosaur. g aItl is quite possible that to be e similar, same n ic lo st r rath racteri of the carnivorous theropod with the speed of.

speed champions were tall and slender creatures, having large eyes in small heads. Perhaps, some of these dinosaurs were omnivorous, although it is believed that in general they were herbivores.

Besides the imitators of birds, there were two other groups of herbivores theropods with outstanding anatomical features. In the oviraptors the crests protrude from their skulls, and in the case of the Therizinosaurus they stood out because of their enourmous claws.

The pachycephalosaurs and ceratopsians form this group whose singular nam e refers to the particular shape of their skulls (Marginoce phalia). The pachycephalos aurs were famous for having heavily ossified skulls load ed with bony prominences and spik es. On the other hand, the ceratopsians’ heads often had horns and bony plat es like gorget, which protruded on their backs from the nec k. It was common to all of them to have a mouth ending in a kind of peak similar to bird s, with two specific bones: the rostral and pre-dental. tal.

Among dinosaurs, the Pachycephalosaurus did not stood out because of its size. This species found in North America could measure up to five meters in length and weig h about two tons. What made it singu lar was the thickness at the top of its skull, reaching up to twenty cent imeters, and because of its protubera nces and spikes distributed around it!

The crests of a hadrosaur

The strange and singular crest of the hadrosaurs has sometimes confused paleontologists. They con sidered these fossils from different species, however, later it was fou nd out that they were just different due to their sexes (sexual dimorphism ) or due to different age s, suc h is the case Another important group Lam beosaurus lambei in the of the ornithopods are the illustration.

In fact, this confusion makes som e dinosaur experts sugges t that the number of species could be a thir d less than what is genera lly thought. Not all scientists believe in evoluti on that seeks, for examp le, transformations of a fish into a reptile, but the K y agree that living things diversify into similar shapes, but different. An example we all understand is found in the case of dogs. There are so many different forms of them that some scientists have considered their variability is equivalent, no longer different species, but for the one there is among different types.

Who has not dreamed of a trip back in time?

Fossils, remains of prehistoric living things, carry a message from the past. In INCREDIBLE DINOSAURS you will find amazing reports brought by these petrified witnesses from the depths of a distant past.

As we will not find any other beings besides dinosaurs capable of blowing a person’s imagination of any age, they have become the protagonists of this book.

Life designs are shown to us again, surprising and full of lessons, whatever their age, as if time has not passed by.

Enjoy the trip‌ to the past!
