Common Name

Styracosaurus is a type of herbivorous dinosaur that lived during the late Cretaceous Period. It’s commonly referred to as a “spiked lizard”.

Scientific Name

The scientific name of Styracosaurus is Styracosaurus albertensis. It belongs to the Ceratopsidae family and was first discovered in Alberta, Canada in 1913 by Charles H. Sternberg.

Size and Appearance

Styracosaurus was a large quadrupedal dinosaur with an average length of 6-7 meters (20-23 feet) and a weight of 2-4 tons. Its body was covered with small spikes, frills, and horns on its skull, neck, shoulders, and tail. Its skull had two large horns above the eyes and a long spike at the back of its head.


Styracosaurus lived during the late Cretaceous period in what is now North America. It is believed to have inhabited open grasslands and woodlands in areas where there were plenty of plants for it to eat.

Styracosaurus was an herbivore that mainly ate plants like ferns, cycads, conifers, and other vegetation. It used its sharp beak to bite off leaves from plants which it then chewed using its tough teeth.

Styracosaurus was thought to have been a social animal that lived in large herds. They were also quite territorial and would use their horns and frills as weapons against potential predators or other Styracosaurus herds.

Anatomy and Appearance of Styracosaurus

Styracosaurus was a genus of herbivorous ceratopsid dinosaur that lived during the Late Cretaceous period, roughly between 76 and 74 million years ago. It was one of the last known non-avian dinosaurs before the Cretaceous–Paleogene extinction event. Styracosaurus had a large, unique head ornamentation consisting of a single horn on its snout, a spiked frill around the back of its head and four long spikes protruding from its frill. The skull was about 1.5 m (4.9 ft) long, making it one of the largest among other ceratopsids. Its body was bulky and heavily built, about 6 m (19.7 ft) in length, with a weight estimated to be around 2 metric tons (4,400 lb). Its tail was relatively short compared to other ceratopsids and its neck was also relatively short compared to other ornithischians.

The overall appearance of Styracosaurus is one of strength and aggression due to its large horns and spikes; it likely used these adornments as visual displays to ward off potential predators or rivals during mating season. The horns on its snout were short but sharp, measuring up to 30 cm (12 in) long in some specimens; the four spikes on its frill were much longer and could measure up to 60 cm (24 in). Its hind legs were longer than its forelimbs, indicating that it may have been bipedal at times; however, it primarily walked quadrupedally like most other ceratopsids. Its feet were flat and broad with hoof-like toes that provided good stability while walking or running on soft substrates such as mud or sand.

The overall colouration of Styracosaurus is unknown since no preserved specimens have been found with intact skin; however, based on comparisons with contemporary species it is assumed that it had a dull brown or grey colouration with possible markings or patterns in lighter shades on certain parts of the body such as the neck or tail regions.


Styracosaurus was an herbivore dinosaur that roamed the Earth during the late Cretaceous Period. It was a large ceratopsian, measuring up to 6 meters in length, and weighing 4 tons. Its behavior is not well known due to a lack of fossil evidence, but it is believed that it lived in herds and was a relatively peaceful creature. It likely fed on low-lying vegetation, such as ferns and cycads, which were abundant during its time. In order to defend itself from predators, Styracosaurus had a large frill on its back that housed several long spikes – thus providing protection from attackers.


Styracosaurus lived in the Western Interior of North America during the late Cretaceous Period. Its fossil remains have been found in Alberta, Canada and Montana and Wyoming in the United States. During this time period, this region would have been a semi-arid environment with coniferous forests interspersed with open grasslands and wetlands. The environment was ideal for Styracosaurus as it provided plenty of food sources while also providing protection from predators.

Feeding Habits of Styracosaurus

Styracosaurus was a herbivorous dinosaur that lived in the late Cretaceous period. It had a double row of four to six long spikes protruding from its neck frill and four long horns on its head, which made it one of the most well-known dinosaurs. Its diet mainly consisted of low-lying vegetation such as ferns, cycads, ginkgos, horsetails and conifers. It would have used its large beak to snap off branches and leaves from trees, then used its small teeth to grind them up before swallowing.

Styracosaurus also had an expandable stomach which allowed it to consume large amounts of food at once, enabling it to survive in periods when food was scarce. Its large size also allowed it to take advantage of larger sources of food such as ground-level vegetation or even carcasses on the ground. This dinosaur was likely an opportunistic feeder, meaning that it would feed on whatever source of food was available at the time.

It is not known exactly how much Styracosaurus ate in a day; however, experts estimate that they likely ate between 4-15 kilograms (9-33 lbs) per day depending on the availability of food in their environment. This would mean that they needed to eat a lot to sustain themselves and their young during their lifetime. Their adaptability and scavenging habits likely helped them survive for millions of years until their eventual extinction at the end of the Cretaceous period.

Reproduction and Life Cycle of Styracosaurus

Styracosaurus is an extinct species of dinosaur that lived during the Late Cretaceous period, about 75 million years ago. Though there is no direct evidence to understand the reproduction and life cycle of Styracosaurus, scientists have been able to make some educated guesses based on the fossil record.

It is believed that Styracosaurus reproduced sexually through internal fertilization. Like other dinosaurs, it is likely that the male Styracosaurus used horns and other physical markers to attract female mates. The female Styracosaurus would then lay eggs in a nest and cover them with dirt or vegetation to protect them. It is possible that they provided some form of parental care, though this has not been confirmed.

The life cycle of Styracosaurus began with hatching from eggs. After hatching, young Styracosaurs would have needed protection from predators until they reached maturity, which could have taken as long as 10 years in some cases. As they grew up, they would have developed horns and frills that were used for defense and display.

Once an adult, the life of a Styracosaurus would have been spent foraging for food and protecting its territory from rival males or predators. It is likely that their diet included plants, insects and smaller animals such as lizards and mammals. They may also have occasionally scavenged carcasses when available.

When a Styracosaurus died, its body would eventually decompose in the environment, returning nutrients back into the soil for other organisms to use. Its remains may also have been scavenged by other animals or left behind as fossils for future generations to discover.

Predators and Threats to Styracosaurus

Styracosaurus were large herbivorous dinosaurs that lived during the Late Cretaceous period. As with many other species of dinosaur, their predators and threats were numerous. The most notable predators of Styracosaurus were Tyrannosaurus Rex, Deinonychus, Gorgosaurus, and Ornithomimus. These powerful predators could easily take down a Styracosaurus with their sharp teeth and claws.

In addition to these predators, Styracosaurus faced threats from other animals in their environment. These threats included large carnivorous mammals such as the saber-toothed cats Smilodon and Homotherium, as well as smaller carnivores like the marsupial Thylacosmilus. All of these animals posed a threat to the Styracosaurus due to their size and strength.

Although there were numerous threats to the survival of Styracosaurus, they had some natural defenses that helped them survive in their environment. One such defense was their armor-like plates along their back which could deflect attacks from predators. They also had a long spiked tail which could be used for defense against predators or foraging competitors. Finally, they had sharp horns on their head which could be used to ward off attackers.

Overall, Styracosaurus faced a variety of predators and threats during the Late Cretaceous period; however, they had some natural defenses that helped them survive in this dangerous environment. With these defenses in place, they were able to thrive until the extinction event that wiped out all non-avian dinosaurs 65 million years ago.


Styracosaurus was a herbivorous dinosaur that lived during the late Cretaceous period, approximately 75 to 70 million years ago. It was first discovered by Lawrence Lambe in 1913 and is a member of the Centrosaurinae subfamily of ceratopsids. Styracosaurus was about 6 meters (20 feet) long, 2 meters (6.5 feet) tall and weighed up to 2 tonnes (4,400 pounds). It had a distinctive skull with a long horn on its head and four large spikes protruding from its neck shield.

Interesting Facts About Styracosaurus

Styracosaurus was an omnivore, meaning it ate both plants and small animals. Its diet likely included low-lying vegetation such as ferns and cycads as well as small lizards, insects and even eggs. The spikes on its neck shield may have been used for defensive purposes or for display during mating rituals. The long horn on its head may have been used for intimidation or to attract mates as well.

The remains of Styracosaurus have been found in Alberta, Canada and Montana and Wyoming in the United States. The most complete specimen was discovered in Alberta in 1951 and is now housed at the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta.

It is believed that Styracosaurus lived in herds like other ceratopsians and scientists believe it would have had an elaborate social structure similar to modern-day elephants or rhinos. Its horns may have been used for both defense against predators such as Tyrannosaurus rex or for fighting between males for dominance within the herd.

Overall, Styracosaurus was a fascinating creature that lived millions of years ago during the late Cretaceous period. Its distinctive skull with horns and spikes helped it stand out among other dinosaurs of the time and makes it one of the most recognizable dinosaurs today!
