\"\"<\/i>Described in 1858, Trematospondylus macrocephalus<\/i> from the Bathonian<\/a> (Middle Jurassic<\/a>) of Germany is one of the earliest established plesiosaur<\/a> taxa<\/a>. However, despite being historically significant, the taxon disappeared from the literature shortly after its initial description and has not been mentioned for over a century. The new study shows that Trematospondylus<\/i> most likely belongs to the Rhomaleosauridae<\/a> and represents a large-bodied member of this archaic clade. The material adds to the rare Middle Jurassic record of rhomaleosaurids and enhances our knowledge of the plesiosaur diversity during the pre-Callovian<\/a> Middle Jurassic, which has been very limited.<\/p>
