The earliest Prehistoric animals to live were jawless, spineless creatures that roamed the oceans about 540 million years ago. It wasn’t until the Devonian period, 400 million years ago, when the prehistoric creatures grew legs and left the ocean, these are the prehistoric ancestors to all vertebrate creatures on earth today. Once on land, the prehistoric creatures underwent a bunch of different adaptations for running, crawling, flying, and jumping; it was then when the rise of the dinosaurs took place, in the Triassic period about 230 million years ago.

Even though the dinosaurs ruled, many small, rodent-like mammals were alive and these small mammals, along with some birds, amphibians, and reptiles survived the mass extinction that wiped out the dinosaurs. Although 90% of the species that have lived on Earth throughout its existence are extinct, most of the creatures that survived this first mass extinction still exist today.

What causes animals to go extinct?

The factors that cause animals to go extinct are mainly the loss and degradation of habitat which is mainly due to deforestation. Other causes for animals going extinct are exploitation through hunting and overfishing, invasive species, and climate change. Plastic pollution and emerging diseases are also factors that play a role in the extinction of animals.

Can extinct animals be brought back?

Extinct animals have not successfully been brought back as of today. Scientists need to sequence its genome and then edit the DNA of a close living relative to match it. Afterwards, they would need to make embryos with the revised genome and have a surrogate mother carry them.

Which animals have gone extinct because of climate change?

Animals that have gone extinct because of climate change include the golden toad and the north Atlantic cod is threatened. The staghorn coral and orange-spotted filefish have also had their population numbers affected by the effects of climate change. It is up to humans to make the necessary changes and help endangered animal species.

Tarpan (Equus ferus ferus)
Dimensioned comparison drawing of the Tarpan compared to an average person

The Tarpan (Equus ferus ferus) also known as Eurasian wild horse was a subspecies of the wild horse that is now extinct. They had a gray coat with a pale underside and a stripe on their back. They also had small ears. The tarpan was native to Russia, but was known to roam all throughout Europe. In the mid-1800s farmers killed them as they were believed to be pests and the last tarpan died in 1909. There have been attempts to ‘breed back’ the tarpan which have resulted in the modern Tarpan that is now referred to as the Heck Horse.

Tarpans have a shoulder height between 48”–52” (122-132 cm), overall standing height of 54.3”-59.8” (138-152 cm), and body length of 70.9”-78.7” (180-200 cm). The weight of a Tarpan is between 661-882 lb (300-400 kg). Tarpans have a typical lifespan of 25-30 years.

Cave Bear (Ursus spelaeus)
Comparison illustration of the size of a Cave Bear to an average human

The Cave Bear (Ursus spelaeus) was a bear species that lived in the Pleistocene region of Europe and Asia and died in the Last Glacial Maximums about 24,000 years ago. The Cave Bear had a very wide and dome-skull with a steep forehead. Its sturdy body had long thighs, large frame, and turning paws, which made it the ancestor to the Brown Bear in its skeletal form. The size of Cave Bears was like those of the largest modern bears.

Male Cave Bears had a shoulder height between 5’-5’7” (1.52-1.7 m) and a weight in the range of 750-1300 lb (340-590 kg). The shoulder heights of females was between 4’7”-5’2” (1.4-1.57 m) with weights from 500-550 lb (227-250 kg). The Cave Bear had an overall body length of roughly 8’8”-11’6” (2.7-3.5 m) and giant upright standing height of 10’-11’6” (3.05-3.5 m).

Dilophosaurus (Dilophosaurus wetherilli)
Scale illustration of an average Dilophosaurus compared to a person

The Dilophosaurus is a theropod dinosaur that lived in North America during the Early Jurassic. In 1940 three skeletons were discovered in northern Arizona, and its genus name, ”two-crested lizard”, honors John Wetherill, a Navajo councilor. It was an active and bipedal species that may have hunted both large and small animals as well as fish. While smaller than some later theropods, the Dilophosaurus was one of the earliest large predatory dinosaurs; it was slender and lightly built with a proportionally large skull. The skill was narrow with a pair of longitudinal, plate-shaped crests.

The Dilophosaurus had an overall length between 16’-20’ (4.88-6.1 m), standing height of 5.7’-7.4’ (1.75-2.25 m), and body width of 15.75”-23.6” (40-60 cm). The weight of the Dilophosaurus was between 650-1,000 lb (295-454 kg).

Protoceratops (Protoceratops andrewsi)
Comparison illustration of the size of a Protoceratops to a person

The Protoceratops is a herbivorous ceratopsian dinosaur that lived in the Upper Cretaceous Period in what is now Mongolia. It was a member of the Protoceratopsidae, a group of early horned dinosaurs. It was a quadrupedal dinosaur that was characterized by its distinctive neck frill at the back of its skull; the frill had two large parietal fenestrae (holes in the frill), and the cheeks had large jugal bones. Comparisons between the scleral rings of the Protoceratops and modern birds and reptiles indicate that the dinosaur had a cathemeral lifestyle- active throughout the day during short intervals.

The Protoceratops had an overall length between 4.9’-5.9’ (1.5-1.8 m), standing height of 19.7”-23.6” (50-60 cm), and body width of 13.8”-19.7” (35-50 cm). The weight of the Protoceratops was between 350-400 lb (159-181 kg).

Styracosaurus (Styracosaurus albertensis)
Size comparison drawing of the Styracosaurus compared to a person

The Styracosaurus is a herbivorous ceratopsian dinosaur that lived in the Cretaceous Period. It means ”spiked lizard” in Ancient Greek, as it had four to six long parietal spikes that extended from its neck frill, a smaller jugal horn on each of its cheeks, and a single horn that protruded from its nose. Other physical characteristics include four short legs, a bulky body, and a short tail. The skull had a beak and shearing cheek teeth arranged in continuous dental batteries; this suggested that the animal sliced up plants. Like other ceratopsians, the Styracosaurus was a herd animal that traveled in groups.

The Styracosaurus had an overall length between 16.4’-19.7’ (5-6 m), standing height of 7.2’-8.9’ (2.2-2.7 m), body width of 3.6’-4.3’ (1.1-1.3 m), and weight from 5,400-6,000 lb (2,450-2,722 kg). The typical lifespan of the Styracosaurus was between 35-45 years.
