Allosaurus

How big did it get? Approximately 28 feet in length.
When did it live? Late Jurassic period (around 155-150 million years ago).
Where did it live? Fossils found in North America, Europe, and possibly Africa.
What did it eat? Carnivorous, likely preying on herbivorous dinosaurs.
Interesting facts? A fearsome predator of the Jurassic period, Allosaurus was a large theropod dinosaur with sharp teeth and a powerful jaw. It likely preyed on herbivorous dinosaurs and was a dominant carnivore in its ecosystem.

When did it live? Late Jurassic period (around 154-150 million years ago).
Where did it live? Fossils found in North America.
What did it eat? Herbivorous, feeding on vegetation with its long neck.
Interesting facts? Characterized by its long neck and whip-like tail, Diplodocus was a herbivorous dinosaur that roamed the Jurassic landscapes. Despite its immense size, it was a gentle giant, using its lengthy neck to reach high vegetation.

Brontosaurus

How big did it get? This massive dinosaur reached lengths of up to 75 feet, with a long neck and tail, and its body towering above the ground
When did it live? Late Jurassic period (around 154-150 million years ago).
Where did it live? Fossils found in North America.
What did it eat? Brontosaurus was herbivorous, relying on its long neck to reach high vegetation and sustain itself on a diet of plants.
Interesting facts? Brontosaurus was initially discovered and named by paleontologist Othniel Charles Marsh in the late 19th century. The name "Brontosaurus" means "thunder lizard." There was a period during which the existence of Brontosaurus as a separate genus was debated in paleontological circles, with some researchers suggesting that it should be classified as a species of Apatosaurus. However, recent studies have reinstated Brontosaurus as a distinct genus, recognizing its unique characteristics. The dinosaur's iconic long neck and massive size have made it a symbol of the grandeur of the Jurassic era.

Archaeopteryx

How big did it get? About the size of a crow, roughly 1-2 feet in length.
When did it live?  Late Jurassic period (around 150 million years ago).
Where did it live? Fossils found in Germany (Europe).
What did it eat? Carnivorous, likely feeding on small insects and other prey.
Interesting facts? Archaeopteryx is considered a transitional fossil between dinosaurs and birds, displaying both reptilian and avian features. It had feathered wings but also teeth in its beak.

Plesiosaurus

How big did it get? Plesiosaurus was a marine reptile with a sleek, elongated body and a relatively small head. It measured around 10 to 15 feet in length, with some species possibly reaching larger sizes.
When did it live? Plesiosaurus existed during the Mesozoic Era, specifically the Jurassic period, around 201 to 145 million years ago.
Where did it live?  Fossils of Plesiosaurus have been found in various locations, including Europe, South America, and North America. The discovery of its fossils in marine deposits suggests a widespread distribution in ancient seas.
What did it eat? Plesiosaurus was carnivorous, preying on fish and other marine creatures. Its sharp, pointed teeth were well-suited for catching and consuming its aquatic prey.
Interesting facts? Plesiosaurus is characterized by its long neck, which sets it apart from other marine reptiles. It had a streamlined body, paddle-like limbs, and likely used its four flippers for efficient swimming. Despite its somewhat serpentine appearance, Plesiosaurus was not a dinosaur but belonged to a group of marine reptiles known as plesiosaurs. The structure of its limbs and body suggest that Plesiosaurus was well-adapted for a semi-aquatic lifestyle, spending much of its time in the open ocean.

 

Compsognathus

How big did it get? This small, bipedal dinosaur measured approximately 3.3 feet in length, making it one of the smaller theropods of its time.
When did it live? Compsognathus existed during the Late Jurassic period, around 150 million years ago.
Where did it live? Fossils of Compsognathus have been found in Europe, with notable discoveries in Germany and France.
What did it eat? Compsognathus was carnivorous, likely preying on smaller animals such as insects, lizards, and possibly small mammals.
Interesting facts? Compsognathus is renowned for its slender build, long legs, and agile nature, traits that suggest it was a swift and nimble predator. Its name, meaning "elegant jaw," reflects the streamlined appearance of its skull. Despite its small size, Compsognathus was likely a proficient hunter, using its speed and agility to pursue prey. Fossil evidence suggests that Compsognathus had feathers, providing valuable insights into the evolution of feathers in theropod dinosaurs.
