Ceratosaurus

Ceratosaurus nasicornis [seh-RAT-o-SAwR-us] [NAY-zih-KOR-nus]

“Horn Lizard”

Ceratosaurus lived in what is now North America during the Kimmeridgian to Tithonian stages of the Late Jurassic period. The first specimen was discovered and excavated by farmer Marshall Parker Felch in 1883 and 1884. located in the Garden Park area north of Cañon City, Colorado, and known as the Felch Quarry. Many fossils have been found outside of North America in Africa, Portugal, and Switzerland.

Ceratosaurus was a medium-sized theropod, the original specimen being is estimated to be 5.3 meters (17 feet) or 5.69 meters (18.7 feet) long from nose to tail, while the specimen described as C. dentisulcatus was larger, at around 7 meters (23 feet) long. Its weight is estimated to be anywhere from  980 kilograms (2,160 pounds) to  275 kilograms (606 pounds) completely depending on the specimen being described.

Ceratosaurus was a theropod dinosaur or a bipedal predator most recognized by its prominent horn on its snout and hornlets above its eyes. These horns were first theorized to be used as a weapon although they were probably not used as a weapon as was originally suggested by Marsh, but more likely were used solely for display.

Ceratosaurus may have preyed upon plant-eating dinosaurs, such as Dryosaurus, although some palaeontologists suggested that it hunted aquatic prey such as fish.

Ceratosaurus is another one of my favourite dinosaurs. I’m not sure what about it is so appealing. It, along with the Acro, are very simplistic compared to most dinosaurs, and yet have such distinctive things to them, such as the sail/humps or hornlets. There are many flashy dinosaurs I love, but I seem to adore Acros and Ceratos more than most, especially more than exhausted dinos such as Tyrannosaurus. Usually, I might draw it covered in fur/feathers, so much so it covers the osteoderms. So again, for the sake of realism, I gave it the suggestion of fuzz on the legs and left the rest up to the imagination.

Acrocanthosaurus

Acrocanthosaurus atokensis [ak-ro-KAN-tho-SAWR-us] [AT-oh-KEN-zis]

“High-spined Lizard”

Acrocanthosaurus lived in what is now North America during the Aptian and Albian stages of the Early Cretaceous. It’s fossil remains are found mainly in Oklahoma, Texas, and Wyoming, although teeth have been found as far as Maryland.

Acrocanthosaurus was among the largest known theropods known to exist, being related to Carcharodontosaurus and Giganotosaurus. The largest known specimen estimated to have been 11.5 meters (38 feet) from nose to tail and weighed 5.7 to 6.2 metric tons.

Acrocanthosaurus was a theropod dinosaur or a bipedal apex predator. It is best known for its high neural spines on its vertebrae. This ridge most likely served as an anchor point for large muscles on its neck and back, although it is often represented as a narrow and colourful sail.

Acrocanthosaurus was the largest theropod in its ecosystem and preyed on sauropods, ornithopods, and ankylosaurids. It had a strong neck and moderately sized arms with three hooked claws on each. Its skull was 1.3 meters (4.3 feet) in length and was long and narrow like most allosauroids.

Acrocanthosaurus is one of my favourite dinosaurs, if not my most. I love this thing and wish it was more popular and well known. I personally prefer giving it a more defined and narrow sail as opposed to a smaller fatter hump, as I feel it makes it appear more distinct compared to a Giga or Charchar. I also, as I do with most of my theropods, give it a small vague amount of fluff or fur-like fuzz on its body, as you can see on its elbows, where it doesn’t really start or end. That’s not meant to imply its completely covered in fur, just that it has some fuff, and is covered in hide rather than scales.
