Elaphrosaurus is a genus of theropod dinosaur that lived during the Late Jurassic period, approximately 154 to 150 million years ago. This dinosaur was first discovered in Tanzania, Africa, and was named by the German paleontologist Werner Janensch in 1920. Elaphrosaurus was a medium-sized, lightly built dinosaur that could grow up to 6.2 meters (20 feet) long.
Elaphrosaurus belonged to the ceratosauria group of theropods and was a carnivorous dinosaur. It had a long neck and tail, and was a fast runner and predator. Paleontologists believe that Elaphrosaurus preyed on small ornithopods, such as Dryosaurus. The dinosaur’s slender build suggests that it was an exceptionally fast runner, although more fossil evidence would be needed to confirm this theory.
Taxonomy
Classification
Elaphrosaurus is a genus of ceratosaurian theropod dinosaur that belongs to the family Ceratosauridae. The genus was named by Werner Janensch in 1920, and the type species is Elaphrosaurus bambergi. Elaphrosaurus is classified under the order Dinosauria, suborder Saurischia, and infraorder Theropoda.
Evolutionary History
Elaphrosaurus lived during the Late Jurassic Period, approximately 154 to 150 million years ago, in what is now Tanzania in Africa. The genus is considered to be an early member of the ceratosaurian clade, which includes other theropods such as Ceratosaurus, Abelisaurus, and Majungasaurus.
Elaphrosaurus was a medium-sized but lightly built member of the group that could grow up to 6.2 m (20 ft) long. Its long neck and tail, and slender, agile legs suggest that it was a fast runner, possibly an efficient predator. The diet of Elaphrosaurus is still debated among paleontologists, but it is believed to have been a carnivore.
In summary, Elaphrosaurus is a genus of ceratosaurian theropod dinosaur that lived during the Late Jurassic Period. It is classified under the family Ceratosauridae and is considered to be an early member of the ceratosaurian clade.

Discovery
Elaphrosaurus is a genus of theropod dinosaur that lived during the Late Jurassic period, approximately 156 million to 144 million years ago. The genus was first discovered in 1910 by a German paleontologist named Werner Janensch. Since then, several fossils of Elaphrosaurus have been found in different parts of the world, including Africa, North America, and Australia.
First Discovery
The first discovery of Elaphrosaurus was made in Tanzania, East Africa, by Werner Janensch. In 1910, Janensch found a partial skeleton of a small theropod dinosaur that he named Elaphrosaurus bambergi. The name ‘Elaphrosaurus’ means “light-footed lizard” in Greek, and it was given to the genus because of its slender and agile build.
Fossil Record
The fossil record of Elaphrosaurus is not very extensive, but it has provided important insights into the diversity and evolution of theropod dinosaurs during the Late Jurassic period. Fossils of Elaphrosaurus have been found in different parts of the world, including Tanzania, Colorado, and Victoria, Australia.
The fossils of Elaphrosaurus are mostly fragmentary, consisting of isolated bones such as vertebrae, ribs, and limb bones. However, some specimens have been found with more complete skeletons, allowing scientists to study the anatomy and behavior of this unique dinosaur.
Description
Elaphrosaurus was a genus of theropod dinosaur that lived during the Late Jurassic period, approximately 154 to 150 million years ago. It was a relatively small and lightweight theropod dinosaur, with a long neck and tail, and slender, agile legs. Elaphrosaurus was distinctive among theropods for being short-legged for its length.
Physical Characteristics
Elaphrosaurus had a long, slender body, with a long neck and tail. Its legs were relatively short for its body size, and its arms were small and not very strong. Elaphrosaurus had a narrow, pointed snout, and its teeth were small and pointed. Its eyes were large and set towards the side of its head, giving it good peripheral vision.
Size and Build
Elaphrosaurus was approximately 6.2 meters long, and its weight is estimated to have been around 210 kilograms. Its long, slender build and agile legs suggest that it was a fast runner, capable of chasing down prey. Its small size and lightweight build would have made it a nimble and elusive target for larger predators.
Overall, Elaphrosaurus was a fascinating dinosaur with unique physical characteristics that set it apart from other theropods of its time. Its long neck and tail, short legs, and small size made it a distinctive and agile predator, well-suited for life in the Late Jurassic period.
Paleobiology
Diet
Elaphrosaurus was a carnivorous dinosaur that fed on small animals such as lizards and mammals. The teeth of Elaphrosaurus were small and pointed, which suggests that it was a predator that fed on small prey. The jaws of Elaphrosaurus were also relatively weak, which suggests that it was not able to take down larger prey.
Locomotion
Elaphrosaurus was a lightly built dinosaur that was able to move quickly. Its long legs and slender body suggest that it was a fast runner. The tail of Elaphrosaurus was also relatively long and light, which suggests that it was used for balance while running.
Habitat Preferences
Elaphrosaurus lived in what is now Tanzania during the Late Jurassic Period. It is believed that Elaphrosaurus lived in a variety of habitats, including forests and open savannas. The fossils of Elaphrosaurus have been found in sedimentary rocks, which suggests that it lived near rivers or other bodies of water.
In summary, Elaphrosaurus was a medium-sized, lightly built dinosaur that was able to move quickly. It was a carnivorous predator that fed on small animals and lived in a variety of habitats. Its fossils have been found in sedimentary rocks near rivers or other bodies of water.
Cultural Impact
In Literature
Elaphrosaurus has made appearances in various works of literature, mainly in books and scientific journals. It has been described in detail in many scientific papers, including those published by the Natural History Museum. The dinosaur has also been mentioned in various books on prehistoric life, including “The Dinosauria” and “The Complete Dinosaur”. These works provide a wealth of information on the dinosaur’s physical characteristics, behavior, and habitat.
In Media
Elaphrosaurus has made several appearances in popular media, including documentaries, video games, and television shows. In the popular video game “Jurassic World Evolution”, players can create and manage their own dinosaur park, and Elaphrosaurus is one of the many species that can be included in the park. The dinosaur has also been featured in several documentaries, including “Dinosaur Planet” and “Planet Dinosaur”. These documentaries provide viewers with a detailed look at the dinosaur’s life and behavior.
Overall, while Elaphrosaurus may not be as well-known as some of the more famous dinosaurs, it has still made a significant impact in the world of literature and media. Its unique physical characteristics and interesting behavior have made it a popular subject for scientific study and popular culture alike.
