Large theropod dinosaurs usually catch our consideration due to their big 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 seemed like primary keratin, like moose antlers, or have been lined in colourful flesh, much like a rooster’s comb, however they have been apparently enticing ultimately to giant predators.
Let’s discover out the highest 10 Dinosaurs with Head Crests
1. Pterosaur
The unbelievable variety of pterosaurs is probably finest expressed in one of many prehistoric flying reptile’s most intriguing and mysterious options: the top crest.
As an example, some pterosaurs had massive, 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 giant bones on the top. “We now know that pterosaur crests had every kind of [bone and flesh] combos,” Hone advised Stay Science.
Through the years, scientists have proposed many attainable functions for these crests, together with that they have been used for warmth regulation or to function rudders throughout flight. “However virtually all the hypotheses have failed essentially the most primary assessments,” Hone stated.
What appears more than likely is that the crests have been used for sexual choice, Hone and his colleagues argued in a 2011 research within the journal Lethaia(opens in new tab).
There are a number of traces of proof that assist this operate of the crests, Hone defined, maybe most notably that juveniles, which appear like miniature variations of grownup pterosaurs, don’t have crests, suggesting the buildings are used for one thing that’s solely related to adults, akin to mating.

2. Dilophosaurus: Two-Crested Dinosaur
Probably the most distinctive (actual) function of the Dilophosaurus is the paired crests atop its cranium, the operate 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 massive or greater than the remainder of its cranium and will have been used to supply sounds, improve its sense of odor, and/or utilized in courtship shows. Lambeosaurus’ nostrils went up by the crest. Its snout was slender and resulted in a beak that was huge and blunt. Males might 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.
Probably the most distinctive function of Lambeosaurus was the oddly formed crest on this dinosaur’s head, which seemed 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 could possibly be so long as 1.8 meters (6 toes) – which is as massive as a person!

Scientists suppose they might 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 suppose they might have gave the impression of.
They have been 10 meters (33 toes) in size and weighed 3.5 tons. Their enormous head crest may 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; No doubt a really fascinating dinosaur, not being extra we are going to uncover every thing 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.
Subsequently, it was hypothesized that among the nasal tissue may 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 lots of of molars.
Saurolophus’ hind legs have been clearly longer and stronger than their entrance legs. As well as, it was capable of 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 known as Protoceratops. On the time of its demise, the oviraptosaur was most likely making an attempt 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 useless animals.
Head crests Completely different oviraptosaurs had otherwise formed crests. A contemporary chicken, the cassowary, has a crest to butt its approach by the forest undergrowth. Maybe oviraptosaurs used their crest for the same objective.

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 that they had a hatched cranium and a protracted tail identical 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 known as a hatchet form. The crests on lambeosaurine hadrosaurids are thought to have served the same objective because the horns and frills of ceratopsian dinosaurs in that they might enable 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’s also attainable that the hole construction of the crest might 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 record 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 well 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 objective of the crest. The one beneficial idea is that the crests have been extremely colored & have been used for identification regarding gender inside 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 by 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, huge beak and lots of of enamel within the again a part of its mouth that it used for grinding powerful crops to mush. Like different duckbills, it was a herd animal that traveled in giant teams. Fossils of this dinosaur are typically discovered along with different plant-eating dinosaurs, which leads scientists to imagine that various kinds of plant-eaters grouped collectively to feed, drink and possibly even migrate (transferring 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 a minimum of twenty people. The crest is much like the helmets worn by historic Corinthian warriors; this resulted in its identify. The crest grew till maturity and was seemingly used as a mating ritual decoration. There seems to be gender differentiation relating to the scale 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 world through the Mid Jurassic interval. That means “Single-crested Lizard,” Monolophosaurus had a rounded crest over its head that may’ve been brightly coloured and used to draw members of the alternative intercourse as properly intimidate rival males.
