Big theropod dinosaurs typically catch our consideration due to their large mouths and enamel. Nonetheless, again within the Mesozoic period, many have been turning heads with the ornamentation on prime of their skulls. We don’t know if the outer look of those crests, spikes, and knobs appeared like fundamental keratin, like moose antlers, or have been coated in colourful flesh, much like a rooster’s comb, however they have been apparently enticing in a roundabout way to massive predators.
Let’s discover out the highest 10 Dinosaurs with Head Crests
1. Pterosaur
The unbelievable range of pterosaurs is probably greatest expressed in one of many prehistoric flying reptile’s most intriguing and mysterious options: the top crest.
For example, some pterosaurs had huge, bony crests, whereas different crests have been fleshy with no underlying bone. Some pterosaurs even seem to have had a saillike crest made up of a membrane sheet connecting two massive bones on the top. “We now know that pterosaur crests had all types of [bone and flesh] combos,” Hone instructed Stay Science.
Through the years, scientists have proposed many doable functions for these crests, together with that they have been used for warmth regulation or to function rudders throughout flight. “However virtually the entire hypotheses have failed probably the most fundamental checks,” Hone stated.
What appears probably is that the crests have been used for sexual choice, Hone and his colleagues argued in a 2011 examine within the journal Lethaia(opens in new tab).
There are a number of traces of proof that help this perform of the crests, Hone defined, maybe most notably that juveniles, which appear to be miniature variations of grownup pterosaurs, don’t have crests, suggesting the constructions are used for one thing that’s solely related to adults, similar to mating.

2. Dilophosaurus: Two-Crested Dinosaur
Essentially the most distinctive (actual) characteristic of the Dilophosaurus is the paired crests atop its cranium, the perform of which stays a thriller. Almost definitely, these crests have been a sexually chosen attribute (that’s, males with outstanding crests have been extra enticing to females throughout mating season, serving to to propagate this trait) or they helped members of the pack acknowledge one another from afar, assuming that the Dilophosaurus hunted or traveled in packs.

3. Lambeosaurus
Lambeosaurus was a crested, duck-billed dinosaur. Its forward-leaning, hole, bony crest was as huge or greater than the remainder of its cranium and should have been used to supply sounds, improve its sense of odor, and/or utilized in courtship shows. Lambeosaurus’ nostrils went up via the crest. Its snout was slender and resulted in a beak that was large and blunt. Males could have had bigger crests than females.
Lambeosaurus grew to be about 30-50 toes lengthy (9-15 m), weighing 5.6 tons. It’s the largest-known duck-bill dinosaur.
Essentially the most distinctive characteristic of Lambeosaurus was the oddly formed crest on this dinosaur’s head, which appeared like an upside-down hatchet—the “blade” protruding from its brow, and the “deal with” jutting out over the again of its neck. This hatchet differed in form between the 2 named Lambeosaurus species, and it was extra outstanding in males than it was in females.
4. Parasaurolophus
This dinosaur had a big crest on its head. On grownup males, this may very well be so long as 1.8 meters (6 toes) – which is as huge as a person!

Scientists assume they could have used their crest to make a trumpeting sound that they used to speak to one another. This video will allow you to hear what scientists assume they could have gave the impression of.
They have been 10 meters (33 toes) in size and weighed 3.5 tons. Their big head crest might develop to 1.8 meters lengthy.

5. Saurolophus
It had a beak like that of a duck and a crest that was not detached in any respect, roughly that was the Saurolophus; Indisputably a really attention-grabbing dinosaur, not being extra we are going to uncover all the things about this dinosaur.
It had a concave bone crest 13 centimeters lengthy in its cranium, pointing backward. This ridge was shaped by the nasal bones and crossed by the nostrils.
Due to this fact, it was hypothesized that a number of the nasal tissue might have been inflatable and allowed the animals to make sounds.
The tip of the decrease toothless beak was barely curved upwards. For grinding plant meals, it had a whole bunch of molars.
Saurolophus’ hind legs have been clearly longer and stronger than their entrance legs. As well as, it was in a position to transfer on two and 4 legs.
6. Oviraptor
The primary oviraptor to be found had a crushed cranium and was mendacity on a nest of fossilized dinosaur eggs. The eggs belonged to an herbivore referred to as Protoceratops. On the time of its demise, the oviraptosaur was most likely attempting to steal the eggs to eat, and since its cranium was crushed, it might have been caught and killed by an grownup Protoceratops. Oviraptosaurs most likely additionally ate berries and bugs, in addition to scavenging on the carcasses of lifeless animals.
Head crests Completely different oviraptosaurs had otherwise formed crests. A contemporary chook, the cassowary, has a crest to butt its manner via the forest undergrowth. Maybe oviraptosaurs used their crest for the same goal.

7. Olorotitan
The big hatchet-like hole crest dinosaur Olorotitan was a hadrosaurid.
This Lambeosaurine-related hadrosaurid was 26 ft (8 m) in size, and the Olorotitan discovery of its fossils made clear that they’d a hatched cranium and a protracted tail similar to most hadrosaurids.
Olorotitan had a particular head crest that rose up from the highest and again of the cranium and pointed backwards in what has been referred to as a hatchet form. The crests on lambeosaurine hadrosaurids are thought to have served the same goal because the horns and frills of ceratopsian dinosaurs in that they’d permit a person to acknowledge others of its personal species from comparable dinosaurs in addition to being coloured to disclose the vitality of the person. Nevertheless it is usually doable that the hole construction of the crest could have acted as a resonating chamber to have an effect on the sound of its calls.
8. Tsintaosaurus
Tsintaosaurus is one more addition to the Lambeosaur household’s listing of controversies: found in 1958 in China, the fossil had an unwieldy bone protruding from an odd angle. This was dismissed as being a sliver of the cranium that had been moved misplaced at some stage throughout its fossilization.
Its invoice, so attribute of the hadrosaurs, was skinny compared to different dinosaurs, it had a physique similar to the likes of Parasaurolophus, a widely known member of the Lambeosaur household. Of the scientists who argue that Tsintaosaurus did have a horn-like crest, these are divided into smaller teams who argue concerning the goal of the crest. The one beneficial principle is that the crests have been extremely colored & have been used for identification regarding gender throughout the herd or standing. It might have flushed with blood when the dinosaur was confronted or scared. One other is that the crest, being hole, was used to make loud sounds by amplifying air blown via from the throat.

9. Corythosaurus
Corythosaurus is a member of the planting-eating, duck-billed dinosaur household that’s typically known as hadrosaurs. It had a toothless, large beak and a whole bunch of enamel within the again a part of its mouth that it used for grinding robust crops to mush. Like different duckbills, it was a herd animal that traveled in massive teams. Fossils of this dinosaur are typically discovered along with different plant-eating dinosaurs, which leads scientists to consider that several types of plant-eaters grouped collectively to feed, drink and perhaps even migrate (shifting from one space to a different).
It’s most well-known for its helmet or half-dinner plate-like crest. It’s recognized from stays belonging to no less than twenty people. The crest is much like the helmets worn by historical Corinthian warriors; this resulted in its identify. The crest grew till maturity and was doubtless used as a mating ritual decoration. There seems to be gender differentiation concerning the dimensions of the crest, with males having a bigger crest.

10. Monolophosaurus
Found in 1981 within the Wucaiwan member of the Junggar Basin within the Shishugou Formation in Xijiang, China, Monolophosaurus was a medium-sized tetanurae theropod dinosaur that stalked the realm through the Mid Jurassic interval. Which means “Single-crested Lizard,” Monolophosaurus had a rounded crest over its head that will’ve been brightly coloured and used to draw members of the alternative intercourse as properly intimidate rival males.
