Seeleyosaurus had a skull about 17 centimeters (6.7 inches) long, with five teeth in the upper jaw and up to 20 teeth in the lower jaw.1
Its flippers were long, making up about 25 percent of its total body length.1
Seeleyosaurus lived during the Toarcian age of the Jurassic period, between 184.2 and 182.9 million years ago.3
The first fossil of Seeleyosaurus was found in the Posidonia Shale, a famous rock formation in Germany known for its well-preserved fossils.31
Scientists once thought Seeleyosaurus was a type of Plesiosaurus, but later studies showed it was its own genus.1
Seeleyosaurus had a short neck compared to some other plesiosaurs, with 35 neck vertebrae.3
The species name guilelmiimperatoris means 'of Emperor William', honoring the German emperor.1
