First Recognized Earth’s Giant Resembles A Sperm Whale

Sperm Whale

Cymbospondylus youngorum is the first known giant creature that ever resided on Earth. Its fossils consist of a head, shoulder joints, and some portions of backbone were found in the Augusta Mountains of Nevada. Their skeletons were first discovered in Germany and England about 250 years ago. They captivated the human imagination as being the greatest reptiles. Since 1902, paleontologists have been excavating the mountains of Nevada. These mountains hint at a link with the ancient aquatic species like octopus, ammonites, and their shelled forefathers. These fossils give us an idea of the competitors and other species at the time of C.youngourum. 

Some Interesting Facts about C.youngourum 

The origin of C.youngourum is traced about 246 million years ago. It mostly fed on squid fish and marine reptiles that its conical teeth show. The animal is thought to be closely related to ichthyosaurs as traditional paleontology suggests it’s a close resemblance with the body of a whale. Evolutionary and ecological analyses were done to examine the fossil ecosystem and its functioning. We know that both ichthyosaurs and cetaceans evolved a huge body but the way they grow gigantic is somewhat different. Ichthyosaurs were born to be of a large size whereas whales took some period to grow up to immense body size standards.

The fossil’s large size and mode of hunting suggested its close link with the sperm whale. Ichthyosaurs and sperm whales have different niches in the food chain making it exceptionally large. The interesting discovery of the latest fossils shows us how the dolphins and whales in front of us today have evolved from their large-bodied ancestors. 

Due to the diversity in their species, these reptiles are thought to be the rulers of aquatic life just as the dinosaurs ruled on land. They evolved fins and hydrodynamic body which made them able to swim through the ocean spreading the food chain. 

While we talk about the excavation process, the vertebrae of these species were found originally, and then sometime later in September, the crew found its skull, chest region, and forelimbs. Its skull is as long as 2 meters that making the species more interesting.  

Competition for Survival 

Due to competition for survival and the presence of many other species, its instinct allowed it to modify the body developing fins and body shape that allowed it to reside and hunt across the aquatic bodies. Through the data collected about ecological conditions, environmental changes, and different fossils at that time, we can guess the energy flow through various sections of the food chain. The large sea whales and friendly dolphins are the primitive species of C.youngourum. However, it is quite a worth noting question that how these species managed to grow to extra-ordinary sizes in record time. The pieces of evidence support this hypothesis that it was undoubtedly the competition that changed the large evolutionary patterns of these organisms.
