Herbivores (A-L)

Herbivores are plant-eating animals.  Learn more about different kinds of herbivorous dinosaurs that roamed the earth many years ago.

  • Anchiceratops  
      
    Anchiceratops was discovered along the Red Deer River in Alberta in 1912. Learn more about the Anchiceratops and Late Cretaceous Dinosaurs.
  • Anchisaurus  
      
    Anchisaurus was one of the first North American dinosaurs described. The first skeleton was found in 1818 and was originally mistake for human fossils. What did this early dinosaur look like and how did it live?
  • Ankylosaurus  
      
    Next to Tyrannosaurus and Triceratops, Ankylosaurus is one of the best-known dinosaurs. Learn more about the Ankylosaurus, Late Cretaceous dinosaurs and dinosaurs of all eras.
  • Antarctosaurus  
      
    With a thigh bone over seven and a half feet long, longer than any other femur known, Antarctosaurus was a sauropod of spectacular proportions. Find out more about this and other Late Cretaceous dinosaurs.
  • Apatosaurus  
      
    Apatosaurus is perhaps one of the most famous dinosaurs because of the size of the animal. A fully grown Apatosaurus could reach up to 70 feet in length. The size of this dinosaur is what earned it the nickname "thunder lizard."
  • Aralosaurus  
      
    Aralosaurus is from Kazakhstan in the Soviet Union. It is known only from a nearly complete skull that is missing the front of the snout and all of the lower jaw, but no skeleton. Learn more about this Late Cretaceous duckbilled dinosaur.
  • Argyrosaurus  
      
    In 1893, British paleontologist Richard Lydekker published the first description of sauropod dinosaurs from South America that had been unearthed in Patagonia, Argentina. One of these was the Argyrosaurus. Learn more about this Late Cretaceous dinosaur.
  • Arrhinoceratops  
      
    Arrhinoceratops is a rare ceratopsian known from only one skull that lacks a lower jaw. This single specimen was found in 1923 along the Red Deer River of Alberta by an expedition from the University of Toronto.
  • Avaceratops  
      
    Avaceratops lammersi was a small ceratopsid known from a single skeleton found in the Judith River Formation of Montana in 1981. Learn more about the Avaceratops and other Late Cretaceous dinosaurs.
  • Bactrosaurus  
      
    Bactrosaurus ("reptile from Bactria") is known from many skull and skeletal pieces, but not a complete skeleton. Learn more about the Bactrosaurus and other Late Cretaceous dinosaurs.
  • Bagaceratops  
      
    Bagaceratops rozhdestvenskyi was a small protoceratopsian with a big name: "baga" is the Mongolian word for "small," "ceratops" means "horned face," and the species name is in honor of Russian paleontologist A. K. Rozhdestvensky.
  • Barapasaurus  
      
    Barapasaurus is named for a word meaning "big leg" in a local dialect in central India. This large dinosaur was a herbivore with large flat teeth that are ideal for cutting or crushing vegetation. What did this dinosaur look like?
  • Brachiosaurus  
      
    The Brachiosaurus is a unique dinosaur because of the placement of the nostril openings, which were slightly above the eyes. Its front legs were longer than the rear, which made it able to eat the leaves from high tree branches.
  • Brachyceratops  
      
    Brachyceratops montanensis was found in 1913 by paleontologist Charles W. Gilmore on the Blackfeet Indian Reservation in Montana. Learn more about the Brachyceratops, Late Cretaceous dinosaurs and dinosaurs of all eras.
  • Brachylophosaurus  
      
    One of the most unusual duckbilled dinosaurs in the Late Cretaceous was Brachylophosaurus ("short-ridged reptile"). This hadrosaurid was discovered and named by Charles Sternberg of Ottawa, Canada, in 1953.
  • Camarasaurus  
      
    One of the most common sauropods of the Late Jurassic was the Camarasaurus. It was a large, 25-ton plant-eater was strong and massive, with powerful legs and a strong neck and tail.
  • Camptosaurus  
      
    Camptosaurus was one of the smallest plant-eating dinosaurs of the Late Jurassic. It weighed no more than 1,000 pounds and stood just five feet tall at the hips. Its strong legs were designed to help it avoid any predators.
  • Centrosaurus  
      
    Centrosaurus, which means "sharp-point reptile," was named by Lawrence Lambe in 1902 from specimens found along the Red Deer River in Alberta. A number of complete skulls and skeletons have since been discovered. Learn more about the Centrosaurus.
  • Cetiosaurus  
      
    Cetiosaurus was a very heavy dinosaur that closely resembled Diplodocus and Apatosaurus. It is thought that the Cetiosaurus is a descendant of those dinosaurs. This was also the first sauropod dinosaur described in 1841.
  • Chasmosaurus  
      
    The first Chasmosaurus fossil found was part of the neck frill. It was unearthed in 1898 by Lawrence Lambe along the Red Deer River, Alberta. Learn more about the Chasmosaurus and other Late Cretaceous dinosaurs.
  • Chungkingosaurus  
      
    There are at least five types of stegosaurs and the Chungkingosaurus was the smallest of all of them. It reached a length of about 12 feet and lived in what is now modern day China.
  • Corythosaurus  
      
    Corythosaurus, the "corinthian helmet reptile," was one of the most abundant duckbilled dinosaurs from the Late Cretaceous of western North America.
  • Dacentrurus  
      
    Dacentrurus was an armored dinosaur that was related to the Stegosaurus. The most prominent feature on this dinosaur was the set of large spikes on the end of the tail. It also had plates of bones on its back just like the Stegosaurus.
  • Datousaurus  
      
    Datousaurus may have been an animal that traveled by itself and ate the leaves of the tallest plants in its environment. It lived in the Middle Jurassic Period in what is now modern day China.
  • Diplodocus  
      
    Diplodocus was an incredibly large dinosaur. It is the longest dinosaur known from complete skeletons. A fully grown adult could reach a length of 90 feet. Skeletons of this massive dinosaur have been found in North America.
  • Edmontonia  
      
    Edmontonia would not have made an easy meal for a hungry tyrannosaur. It had a heavily armored body and large, forward-pointing shoulder spines. Learn more about Edmontonia, Late Cretaceous dinosaurs and dinosaurs of all eras.
  • Edmontosaurus  
      
    Edmontosaurus was one of the largest hadrosaurids. This flat-headed duckbilled dinosaur was originally found, described, and named by Lawrence Lambe in 1920. Learn more about the Edmontosaurus and other Late Cretaceous dinosaurs.
  • Elmisaurus  
      
    The Joint Polish-Mongolian Paleontological Expeditions of the 1960s produced many new kinds of dinosaurs, many of which were small theropods. One of these theropods was a Elmisaurus. Learn more about Elmisaurus.
  • Erlikosaurus  
      
    In 1980, Altangerel Perle named Erlikosaurus andrewsi after the demon Erlik from Mongolian mythology and paleontologist Roy Chapman Andrews. It was closely related to Segnosaurus. Learn more about the Erlikosaurus.
  • Euhelopus  
      
    The Euhelopus is a very large dinosaur that lived in what is now China. Only a partial skeleton of this animal has been found, but it is estimated that it weighed between 15 and 20 tons.
  • Euoplocephalus  
      
    Euoplocephalus lived at the same time and in the same areas as Edmontonia. Euoplocephalus roamed the forests cropping low plants with its broad beak. It probably ate any type of plant it came across.
  • Garudimimus  
      
    Garudimimus brevipes was one of many dinosaurs found by the Joint Soviet-Mongolian Paleontological Expeditions of the 1970s. It was named for the Garuda bird of Hindu mythology; its name means "short-footed Garuda mimic."
  • Goyocephale  
      
    The flat-headed Goyocephale was one of the most unusual pachycephalosaurs. It was found by the Joint Polish-Mongolian Paleontological Expeditions to the Gobi Desert, and was named and described in 1982. Learn more about the Goyocephale.
  • Hadrosaurus  
      
    Hadrosaurus ("thick reptile") was the first hadrosaur skeleton to be discovered. It was named and described in 1858 by Joseph Leidy, the father of American paleontology.
  • Heterodontosaurus  
      
    Heterodontosaurus is a small plant eating dinosaur that most likely walked on its hind legs. An unusual feature on this dinosaur is a pair of tusks that probably helped with eating. What else do we know about this tiny dinosaur?
  • Homalocephale  
      
    As its name ("even head") suggests, Homalocephale had a flat head unlike most pachycephalosaurs. It is known from limited but very good material. The single skull of Homalocephale is missing the front of the snout but is otherwise complete.
  • Huayangosaurus  
      
    Huayangosaurus was a type of stegosaur that lived in the Middle Jurassic in what is now China. The most prominent feature on this dinosaur is the rows of bony plating that ran down its back.
  • Hypacrosaurus  
      
    The head of Hypacrosaurus looked much like Corythosaurus. The snout was somewhat ducklike, although the nostrils were in slightly different places. Learn more about the Hypacrosaurus and other Late Cretaceous dinosaurs.
  • Iguanodon  
      
    This dinosaur got its name, "iguana tooth," because its tooth looked like those of an iguana. It was a large ornithopod and walked on its stocky back legs. Discover if it was a plant or meat eater.
  • Kentrosaurus  
      
    Kentrosaurus stands out among its relative stegosaurs because this dinosaur had an extra set of spines that stuck out above its hips. It had short front legs and neck which means it could only eat low shrubs and plants.
  • Kritosaurus  
      
    Kritosaurus was a large, flat-headed duckbilled dinosaur. It had a ridge of bone between the eyes and the snout that gave it a distinguished "Roman nose" appearance.
  • Lambeosaurus  
      
    Lambeosaurus lived at the end of the Late Cretaceous. It was a hollow-crested hadrosaurid that lived at the same time and in the same places as Corythosaurus and Parasaurolophus.
  • Leptoceratops  
      
    Leptoceratops, the first known protoceratopsid, was found along the Red Deer River of Alberta, Canada, in 1910. This partial skull and skeleton was named Leptoceratops gracilis.
  • Lesothosaurus  
      
    Lesothosaurus was a dinosaur that measured about three and a half feet in length and was build for running. It had hollow bones and hollow spaces in the skull. What was this dinosaur's behavior like?
