Dinosaur Names Beginning with ‘S’: A Journey Through Prehistoric Times

When you think about dinosaurs, the first names that probably come to mind are the T-Rex or the Velociraptor. But have you ever wondered about dinosaurs that start with ‘S’? There’s a wide range of fascinating creatures whose names begin with this letter, and we’re here to take you on a journey through prehistoric times to discover them.

Understanding the Dinosaur Era

Before we delve into our list of dinosaur names starting with ‘S’, let’s take a moment to understand the era in which these magnificent creatures roamed the Earth. The Mesozoic Era, often referred to as the “dinosaur era name“, spanned from 252 to 66 million years ago. This era was divided into three periods: Triassic, Jurassic, and Cretaceous, each of which witnessed the rise and fall of different dinosaur species.

Dinosaur Names Starting with ‘S’

Now, let’s explore some of the most interesting dinosaurs whose names start with ‘S’. From small, agile hunters to massive, herbivorous giants, these dinosaurs are as varied as they are intriguing.


The Stegosaurus is perhaps one of the most well-known dinosaurs that start with ‘S’. This large, herbivorous dinosaur lived during the Late Jurassic period. Its name, derived from Greek words, means “roofed lizard”. The “stegosaurus name meaning” aptly describes the distinctive plates along its back and tail, which it used for thermal regulation and defense against predators.


The Spinosaurus, whose name means “spine lizard”, was a carnivorous dinosaur that lived during the Cretaceous period. It’s known for its distinctive sail-like structure on its back, which was likely used for display and temperature regulation.


The Sauroposeidon is one of the long names that start with ‘S’. This dinosaur was a massive, long-necked creature that roamed North America during the Early Cretaceous period. Its name means “earthquake god lizard”, hinting at its enormous size and strength.


The Suchomimus, another fascinating dinosaur starting with ‘S’, was a large, fish-eating dinosaur from the Cretaceous period. Its name translates to “crocodile mimic”, referencing its crocodile-like skull and sharp, curved claws.

Long Names Beginning with ‘S’

Many dinosaur names are quite lengthy, particularly those beginning with ‘S’. In addition to the Sauroposeidon, here are two more examples:


The Styracosaurus, or “spiked lizard”, was a herbivorous dinosaur from the Cretaceous period. It’s known for its large frill and multiple long horns, making it one of the most striking dinosaurs that start with ‘S’.


As the name suggests, the Supersaurus was indeed super in size. This long-necked, long-tailed dinosaur was one of the longest creatures ever to walk the Earth. Its name, another long name starting with ‘S’, means “super lizard”.

Names Starting with ‘San’

Interestingly, some dinosaur names even start with ‘San’. One example is the Santanaraptor, a small, carnivorous dinosaur from the Early Cretaceous period. Its name refers to the Santana Formation in Brazil, where its fossils were discovered.


From the Stegosaurus to the Supersaurus, dinosaurs whose names start with ‘S’ offer a fascinating glimpse into our planet’s prehistoric past. Each of these creatures, whether known for their size, unique features, or the era they lived in, contributes to our understanding of life on Earth millions of years ago. So, the next time you think about dinosaurs, remember that there’s a whole alphabet of dinosaur names to explore, each with its own story to tell.
