Dinosaurs That Start With I

Dinosaurs have always been a topic of interest for humans, inspiring movies, series, documentaries, and even academic fields of study. These magnificent beasts ruled the planet for millions of years. The word “dinosaur” means “terrible lizard” in Greek, though scientists have discovered that some dinosaurs were feathered and even flew. However, most of these reptiles were land dwellers, and they all have unique skeletal structures, shapes, and sizes. Some species were gentle giants, while others were formidable hunters, making them the ultra predators of their time. Regardless of their classification, all dinosaurs played a crucial role in shaping the history of life on Earth.

Compiling this list took much longer than I anticipated. It was a meticulous process that required attention to detail and an understanding of what makes these creatures unique. But the end result was worth all the long hours of research, as the list encompasses everything that makes these prehistoric beings so fascinating.

So, let’s begin exploring this list of dinosaurs starting with I!

And here’s the list of dinosaurs that begin with I letter.

Iani

Iani was a small, bipedal carnivorous dinosaur that lived during the early Jurassic period. It was a member of the Coelophysoidea family, characterized by their long slender legs and a long tail used for balance. Iani was a fast runner and agile predator, with sharp, serrated teeth that it used to tear apart its prey.

Iberospinus

Iberospinus was a stegosaur that lived during the Late Jurassic period. It was named after the Iberian Peninsula where it was discovered and its distinctive rows of bony spikes that ran down its back. It was a large and heavily-armored herbivore, with a broad, triangular skull and a beaked mouth that it used to crop vegetation. Despite its size, it was also surprisingly agile, able to twist and turn its body to avoid attacks from predators such as the Allosaurus.

Ibirania

Ibirania was a small, bipedal carnivorous dinosaur that lived during the Late Cretaceous period. It was part of a diverse group of dinosaurs known as theropods, characterized by their hollow bones and three-toed feet. Ibirania was a fast runner and hunter, with a slender body and a long tail that helped it maintain balance and control when stalking prey.

Ichthyovenator

Ichthyovenator was a large, piscivorous dinosaur that lived during the Early Cretaceous period. This unusual dinosaur had a sleek, streamlined body that was built for swimming and a long, toothy snout that it used to catch fish and other aquatic prey. Although it spent most of its time in the water, it was also capable of walking on land and may have pursued terrestrial prey at times.

Ignavusaurus

Ignavusaurus, also known as the lazy lizard, was a genus of herbivorous dinosaur that lived during the Early Cretaceous period. Despite its name, it was actually a moderately active creature that spent most of its time grazing on low-lying vegetation. It was a quadrupedal dinosaur with a bulky body and a small head, and would have been vulnerable to predators such as the Utahraptor.

Ignotosaurus

Ignotosaurus was a genus of ornithopod dinosaur that lived during the Early Cretaceous period. Although it is known primarily from fragmentary fossils, researchers believe that it was a small, bipedal herbivore with a slender, agile body and powerful hind legs. It likely lived in small herds and used its sharp beak to strip leaves and other vegetation from low-lying branches.

Iguanacolossus

Iguanacolossus was a genus of herbivorous dinosaur that lived during the Early Cretaceous period. It was a relatively large dinosaur, reaching lengths of up to 30 feet, and had a massive, heavily-armored body. Its most distinctive feature, however, was the distinctive hump on its back that may have served as a display structure or a fat storage reservoir during periods of food scarcity.

Iguanodon

Iguanodon was a genus of herbivorous dinosaur that lived during the Early Cretaceous period. It was a large, bipedal dinosaur with a distinctive thumb spike that it likely used for self-defense. It was also one of the first dinosaurs to be scientifically described, with the first fossils being discovered in England in the early 19th century.

Iliosuchus

Iliosuchus was a genus of carnivorous dinosaur that lived during the Late Cretaceous period. It was a relatively small dinosaur, reaching lengths of only around 6 feet, and was characterized by its long, crocodile-like snout and sharp, serrated teeth. Although it was a deadly predator, it was also preyed upon by larger dinosaurs such as the Tyrannosaurus rex.

Ilokelesia

Ilokelesia was a genus of herbivorous dinosaur that lived during the Late Cretaceous period. It was a massive, quadrupedal dinosaur with a heavily-armored body and a distinctive bony crest on its head. This crest likely served as a display structure or as a means of attracting a mate, and would have been visible from miles away.

Imperobator

Imperobator was a genus of carnivorous dinosaur that lived during the Late Cretaceous period. It was a large, bipedal predator with sharp, serrated teeth and powerful legs. Although it was a fearsome predator, it was also likely preyed upon by larger dinosaurs such as the Tyrannosaurus rex.

Incisivosaurus

Incisivosaurus was a genus of herbivorous dinosaur that lived during the Late Cretaceous period. It was a small, bipedal dinosaur with a sleek, streamlined body and a beaked mouth that it likely used to graze on low-lying vegetation. It is named after its distinctive front teeth, which were long and pointed and used to strip plant material from its food.

Indosaurus

Indosaurus was a genus of carnivorous dinosaur that lived during the Late Cretaceous period. It was a relatively small predator, reaching lengths of only around 6 feet, and was characterized by its sharp, curved teeth and powerful jaws. Although it was smaller than many of its contemporaries, it was still a dangerous predator that likely preyed upon small mammals and other reptiles.

Indosuchus

Indosuchus was a genus of carnivorous dinosaur that lived during the Late Cretaceous period. It was a massive predator, reaching lengths of up to 30 feet and characterized by its massive skull and powerful jaws. Although it was one of the largest carnivorous dinosaurs of its time, it was also relatively slow-moving and may have relied on ambush tactics to catch its prey.

Ingentia

Ingentia was a genus of huge herbivorous dinosaurs that lived during the Late Triassic period. It was one of the largest dinosaurs of all time, reaching lengths of up to 60 feet and weighing over 20 tons. Despite its massive size, however, it was relatively agile and had a long, powerful tail that it likely used to maintain balance and control.

Inosaurus

Inosaurus was a genus of carnivorous dinosaur that lived during the Late Jurassic period. It was a relatively small predator, reaching lengths of only around 6 feet, and was characterized by its sharp, pointed teeth and agile, bipedal body. Although it was small, it was still a lethal predator that likely preyed upon small reptiles and mammals.

Invictarx

Invictarx was a genus of armadillo-like dinosaur that lived during the Late Cretaceous period. It had a heavily-armored body covered in bony plates and a beaked mouth that it likely used to graze on low-lying vegetation. Although it was heavily armored, it was still vulnerable to large predators such as the Tyrannosaurus rex.
