Syngonosaurus is an extinct type of dinosaur that lived a long time ago, in the Early Cretaceous period, around 105 to 100 million years ago.
This dinosaur belonged to a group known as ornithopods, specifically called iguanodontians. It was first discovered in an area called Cambridge Greensand in England and was named by a scientist named Harry Seeley in 1879.
The main species of this dinosaur is called Syngonosaurus macrocercus. At first, it was thought to be part of a different dinosaur group called Acanthopholis. However, in 2020, scientists re-evaluated it and decided that Syngonosaurus should stand on its own again as a unique genus.
The discovery of Syngonosaurus began when Seeley identified several new species in 1869 based on fossils he found. These fossils included the remains of Syngonosaurus. Later, in a study in 1999, researchers reviewed the old findings and concluded that some were mixed up with other dinosaur types.
Despite confusion about its classification over the years, recent studies have helped clarify that Syngonosaurus belongs to the iguanodontian group.
So, in summary, Syngonosaurus is an interesting dinosaur that helps us understand more about the diversity of life on Earth millions of years ago.
