Animal Families & Genera

Dinosaurs | Dinosauria

Dinosaurs are a diverse group of prehistoric reptiles that were the dominant terrestrial animals of the Late Triassic (251.9-201.3 Mya), Jurassic (201.3-145 Mya), and Cretaceous (145-66 Mya) periods. Discovered and studied since the 19th century, dinosaur fossils found around the world have been used by paleontologists to identify over 1,000 different species of dinosaurs.

Dinosaurs are commonly categorized by distinctive traits ranging from variations of bipedal (2 legs) or quadrupedal (4 legs), body armor or feathers, herbivorous or carnivorous, and quick or slow movement speeds. Though dinosaurs mysteriously disappeared 65 million years ago, their legacy continues to be popularized in museums, books, films and television.

When did dinosaurs live?

Dinosaurs lived in the Mesozoic Era which took place between 245 and 66 million years ago. The Mesozoic Era is divided into 3 time periods: Triassic (252 to 201 million years ago), Jurassic (201 to 145 million years ago), and Cretaceous (145 to 66 million years ago).

Why were dinosaurs so big?

Paleontologist believe dinosaurs grew so big in order to gain protection from predators, help regulate internal body temperature, and to allow them to reach their source of food. Today, whales are the only animal who are close to the size of dinosaurs.

Where did dinosaurs live?

Dinosaur fossils have been found on every continent, proving that they lived in every environment of the world. During the Triassic period the continents were one supercontinent called Pangea. The continents slowly spread across the world into the arrangement that they are at today.

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).

Iguanodon (Iguanodon bernissartensis)

Scale illustration of an average Iguanodon compared to a person

The Iguanodon lived about halfway between the first of the swift bipedal hypsilophodontids of the mid-Jurassic and the duck-billed dinosaurs of the late Cretaceous. It is an ornithopod dinosaur that lived in Belgium, Spain, German, England, and in other parts of Europe. It was a large and bulky herbivore; other distinctive features include large thumb spikes, for defense against predators, and long prehensile fifth fingers used to forage food. It is one of the first scientifically well-known dinosaurs, and it also has a notable place in the public’s perception of dinosaurs.

The Iguanodon had an overall length between 29.5’-39.4’ (9-12 m), standing height of 11.5’-15.75’ (3.5-4.8 m), body width of 3.9’-5.25’ (1.2-1.6 m), and weight from 8,000-11,000 lb (3,629-4,990 kg). The typical lifespan of the Iguanodon was between 25-40 years.

Argentinosaurus (Argentinosaurus huinculensis)

Comparison illustration of the size of a Argentinosaurus to a person

The Argentinosaurus is a sauropod dinosaur that lived in the Late Cretaceous period in modern day Argentina. Its generic name means ”Argentine Lizard”. While only known from fragmentary remains, the Argentinosaurus is one of the largest-known land animals of all time, if not the largest. Because of the fragmentary nature of the remains, the Argentinosaurus’ interpretation is difficult, as there are multiple arguments around the position of the recovered vertebrae within the vertebral column. The first remain, a fibula, was discovered by Guillermo Heredia in 1987 on his farm in Neuquen Province, Argentina.

The Argentinosaurus had an overall length between 98’-115’ (30-35 m), standing height of 39.4’-45.9’ (12-14 m), body width of 12.5’-14.8’ (3.8-4.5 m), and weight from 110,000-220,000 lb (49,895-99,790 kg). The typical lifespan of the Argentinosaurus was between 35-45 years.

Corythosaurus (Corythosaurus casuarius)

Comparison illustration of the size of a Corythosaurus to a person

The Corythosaurus is a hadrosaurid ”duck-billed” dinosaur that lived in the Upper Cretaceous Period. Its name translates to ”helmet lizard” in Greek for its skull with tall crests; the crests are similar to those of the cassowary and a Corinthian helmet. These functioned as a tool in vocalization for the dinosaur. It was preserved with its last meal, conifer needles, seeds, twigs, and fruits, inside the chest cavity. The first Corythosaurus was discovered by Barnum Brown in 1911 in Red Deer River, Alberta, Canada, and the find was notable because impressions of the creature’s skin had also survived.

The Corythosaurus had an overall length between 30’-33' (9.14-10 m), standing height of 15.1’-17.4’ (4.6-5.3 m), body width of 3.3’-3.9’ (1-1.2 m), and weight from 6,000-11,000 lb (2,722-4,990 kg). The typical lifespan of the Corythosaurus was between 60-70 years.

Set of scaled drawings of the Corythosaurus with dimensions

The Corythosaurus is a hadrosaurid ”duck-billed” dinosaur that lived in the Upper Cretaceous Period. Its name translates to ”helmet lizard” in Greek for its skull with tall crests; the crests are similar to those of the cassowary and a Corinthian helmet. These functioned as a tool in vocalization.

The Corythosaurus had an overall length between 30’-33' (9.14-10 m), standing height of 15.1’-17.4’ (4.6-5.3 m), body width of 3.3’-3.9’ (1-1.2 m), and weight from 6,000-11,000 lb (2,722-4,990 kg). The typical lifespan of the Corythosaurus was between 60-70 years.

Allosaurus (Allosaurus fragilis)

Scale illustration of an average Allosaurus compared to a person

The Allosaurus is a carnivorous theropod dinosaur that lived during the late Jurassic period. Its name, which translates to ”different lizard”, is in reference to its unique concave vertebrae. As a large bipedal predator, the Allosaurus had a large skull with many sharp, serrated teeth. It had powerful hindlimbs and a long muscular tail, with smaller forelimbs in comparison. With these physical characteristics, the Allosaurus was at the top of the food chain with a diet that included herbivorous dinosaurs like ornithopods, stegosaurids, and sauropods. The species was first discovered in 1877 by Othniel Charles Marsh, a paleontologist.

The Allosaurus had an overall length between 26’-43’ (7.9-13.1 m), standing height of 9.5’-16.1’ (2.9-4.9 m), body width of 3.3’-5.25’ (1-1.6 m), and weight from 3,300-5,070 lb (1,497-2,300 kg). The typical lifespan of the Allosaurus was between 25-30 years.
