The evolution of the rhinoceros and a look at the past of this animal until today

30 million years ago in what is now Pakistan the shadow of the largest animal of that time covered the Horizon and the landscape resembled a

savannah this animal was a parasaran and one of the largest mammals that ever

existed its body shape was similar to that of a giraffe but giraffes were supposed to evolve in 20 million years and even though it was very big it had nothing to do with

elephants in fact it was most similar to rhinoceroses however his skull probably carried a

hook the reason is that while the five species of rhinoceros that are alive today are very similar and are on the verge of Extinction the larger family that included the rhino osus was once much larger and more mature and was spread far north than today and survived in a colder

climate in this program we take a look at the evolution of the

rhinoceros the first fossilized ancestor of the rhinocerus was a small creature called hdon which lacked horns and was about the size of a

pig about 50 million years ago he lived in North America during the esine period when the global temperature was much higher than today so their American habitat must have been a mass

Forest at this point in history the closest living relatives of rhinoceroses are horses and tapers whose an an cestors were hard to tell apart in the early

esine this is because they all live in the same way and have less time to diversify in different

places but this is also a general law of evolution that the more you go back the more similar animals become because they are closer to each

other horses rhos es and tapers are the only living descendants of a group of animals called perissodactyls which are classified by the fact that they have an odd number of

fingers and they balance most of their weight on their middle finger compared to most hoofed animals known as aratiles they distribute more weight on their two middle fingers

today Ry and dactyls are much more numerous than perissodactyls and they are large herbivores that inhabit most

ecosystems but around 25 to 45 million years ago the perissodactyls were much more

numerous for example there is a group of perissodactyls called Chalik cotters that have claws and some of them have a gorilla-like body shape with front legs longer than their hind

legs but like all perissodactyls their oldest ancestors were small four-legged hunter gatherers similar to

haradon perissodactyls also include a group of prehistoric animals called Broner which are very similar to

rhinoceroses however this similarity was only due to their convergent evolution and in fact they were closer to horses and even much

older they lived in the esin period and became extinct about 35 million years ago which was the period when roseros began to

evolve this was the beginning of an era called the oligoene roughly between the present and the extinction of the non-avian

dinosaurs dinosaurs have been extinct for a long time and now they are ruling mammals and have a lot of punishment but the big mammal families that we know today rarely evolved and instead the land habitats were full of different but similar

mammals cats and dogs have just evolved and are small and definitely not among the most powerful

Hunters instead the largest carnivorous species are known as cens a group of mammals that have many of the same hunting characteristics as as cats and dogs such as retractable sharp

claws at this point in history the largest mammals were a group of long snout rhinoceroses called Pariser

Arians but it was not only Pariser trium and in fact the whole family of rhinoceros became significantly more numerous during this period and they are even more numerous than they are today at some point in their evolution the rhinoceros family split real rhinoceroses are known as rhinoceri and long necked rhinocerus as

paracer first parisera totis had a relatively large size the first paracer toids found in fossils lived in China and they were almost the same size as a horse both in terms of height and size most species of the no paracer toian were about this size from a horse about the size of a wild deer but later in the oligos scene a member of this group

evolved and became the largest land animal since the extinction of non-avian dinosaurs Pariser trium was first associated with rhinoceroses due to teeth and parts of the brain found in Pakistan and when it was discovered it was thought to be just basically a rhinoceros of course with a huge amount to justify the size of the discovered fossils almost immediately these images were revised to an animal with a longer neck and legs due to the discovery of some longer vertebrae and limb
