Dinosaurs That Start With H

Dinosaurs! These creatures have roamed the Earth before us humans and left us in awe with their existence, behavior, and extinction. Fossil records suggest that they lived during the Mesozoic Era, known also as the Age of Dinosaurs, for more than 150 million years. Scientists have identified and classified over 700 different species of dinosaurs, each with its unique features. From the herbivorous mighty long-necked Sauropods to the meat-eating Tyrannosaurus Rex, every type of dinosaur had its special niche in the ecosystem. Although these creatures have vanished from the face of the earth, their legacy still lives on and fascinates people of all ages today.

At first, I thought compiling a list of dinosaurs would be an easy task. However, it turned out to be quite the opposite. There were countless species and information that had to be considered. But I was determined to create an accurate and comprehensive list, and my perseverance paid off.

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

60 Dinosaurs That Start With H

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

Hadrosaurus

Hadrosaurus was a herbivorous dinosaur that lived around 70 million years ago in North America during the Late Cretaceous period. These ducks-billed dinosaurs were large and they had an impressive dental battery, which was able to grind tough plant material. Hadrosaurus possessed a unique elongated nasal passage that may have given them an elaborate vocalization repertoire.

Haestasaurus

Haestasaurus was an enormous sauropod dinosaur that lived about 140 million years ago during the Early Cretaceous period in South America. This dinosaur belongs to the titanosaur family and was one of the largest land animals that ever lived. Haestasaurus probably had an extremely long neck and a relatively small head, inhabited coastal areas and may have fed on shallow water vegetation.

Hagryphus

Hagryphus is a small bird-like dinosaur, measuring only three feet in length, that lived during the Early Cretaceous period in Mongolia. It belongs to the group called “oviraptorosaurs”, which was characterized by the lack of teeth and the presence of sharp beaks. Hagryphus likely fed on small animals such as insects and lizards, also it had a feathery coat similar to modern birds.

Hallopus

Hallopus was a fast-running carnivorous dinosaur that lived approximately 205 million years ago during the Late Triassic period in North America. This dinosaur belonged to the theropod family and had a slender build, long legs and a light skull filled with sharp teeth. Hallopus was probably an agile predator that preyed on small-sized herbivorous dinosaurs.

Halszkaraptor

Halszkaraptor was a bizarre-looking dinosaur that lived around 75 million years ago during the Late Cretaceous period in Mongolia. Its appearance is unique in the dinosaur kingdom, it was a water-dwelling theropod that was able to swim thanks to its long flippers. Halszkaraptor was a small dinosaur, with a long and slender neck, a toothless beak and sharp claws on its forelimbs.

Halticosaurus

Halticosaurus was a small herbivorous dinosaur that lived around 168 million years ago during the Middle Jurassic period in Europe. This dinosaur belongs to the group of “hypsilophodontids” which were small, agile and fairly smart herbivores that likely ate low-lying vegetation. Halticosaurus had long rear legs providing excellent speed for escaping predators.

Hamititan

Hamititan was a gigantic sauropod dinosaur that lived around 160 million years ago during the Middle Jurassic period in China. This dinosaur belongs to the group of “mamenchisaurids”, which were characterized by their extremely long necks – estimated an average of up to 35 meters – and long tails. Hamititan was a herbivore and likely consumed large quantities of vegetation per day, still there are doubts about how it could support the weight of its long neck.

Haplocanthosaurus

Haplocanthosaurus was a large herbivorous dinosaur that lived about 150 million years ago during the Late Jurassic period in North America. Haplocanthosaurus had a stocky build and strong legs that allowed it to support its massive weight. This dinosaur had a long neck with a small head, and had a unique spiky structure located on its collarbone, which possibly served as a defensive weapon, or played a role in display.

Haplocheirus

Haplocheirus was a carnivorous dinosaur that lived about 160 million years ago during the Middle Jurassic period in China. It belongs to the group of “alvarezsaurids”, which were characterized by their tiny arms, with the hand consisting of only one finger. Haplocheirus had a long snout, sharp teeth, was agile and likely hunted small animals.

Harpymimus

Harpymimus was a small omnivorous dinosaur that lived approximately 70 million years ago during the Late Cretaceous period in Mongolia. This dinosaur belongs to the group of “ornithomimosaurs” which generally lacked teeth and were therefore likely herbivorous. Harpymimus had long legs, lightweight and a long tail. Its name honors a mythological creature known as the Harpy.

Hecatasaurus

Hecatasaurus was a herbivorous dinosaur that lived around 190 million years ago during the Early Jurassic period in South Africa. This dinosaur belongs to the group of “sauropodomorphs” and was relatively small, with an estimated length of only about six meters. Hecatasaurus had a long neck, a small head and was likely a slow-moving animal.

This dinosaur belongs to the group of “sauropodomorphs” and had a long neck allowing it to reach high vegetation, a long tail and powerful legs. Heishansaurus likely moved around in large herds.

Helioceratops

Helioceratops is a small plant-eating dinosaur that lived about 105 million years ago during the Early Cretaceous period in China. This dinosaur belongs to the group of “ceratopsians” and had a distinctive frill with small horns and a short beak similar to the modern parrot. Helioceratops likely lived in small family groups and they would protect themselves from predators with their sharp beaks and hooks.

Herbstosaurus

Herbstosaurus was a herbivorous dinosaur that lived about 260 million years ago during the Late Permian period in South Africa. This dinosaur belonged to the group of “dicynodonts” and had a beak-like jaw with the ability to chew tough vegetation. Herbstosaurus likely originated from the lineage that ultimately gave rise to modern mammals.

Herrerasaurus

Herrerasaurus was a carnivorous dinosaur that lived around 231 million years ago during the Late Triassic period in South America. This dinosaur was one of the earliest large predatory dinosaurs that existed and belongs to the group of “herrerasaurids”, characterized by a slender skull and serrated teeth. Herrerasaurus was one of the top predators of its time, although it was much smaller than the later giant theropods.

Hesperornithoides was a small carnivorous dinosaur that lived around 150 million years ago during the Late Jurassic period in North America. This dinosaur belongs to the group of “theropods” and had long legs, sharp teeth, and claws. Hesperornithoides had feathers that possibly helped it to camouflage itself in the environment.
