Iuticosaurus (meaning "
sauropod dinosaur from the Early Cretaceous of the Isle of Wight.[1] Two species have been named: I. valdensis and I. lydekkeri.[2] I. valdensis was found in the Wessex Formation and I. lydekkeri in the younger Upper Greensand
.
History and taxonomy
In 1887
Harry Govier Seeley and John Hulke for his choice and in 1888 he referred to the fossils as Titanosaurus sp. a, Titanosaurus sp. b being a third vertebra, BMNH 32390.[4]
In 1929 Friedrich von Huene named both taxa as full species. The first became Titanosaurus Valdensis, the specific name referring to the Wealden, the second Titanosaurus Lydekkeri, its specific name honouring Lydekker.[5] By present convention both specific names would be spelled as T. valdensis and T. lydekkeri respectively.
In 1993
lectotype. Another vertebra, BMNH R 1886, was referred by him to this species. The second species, though formally named by him as Iuticosaurus lydekkeri, he considered a nomen dubium.[2]
Description
Iuticosaurus was probably similar to Titanosaurus. It measured 15 to 20 metres (49–65 feet) long.[2]
Classification
Most researchers have concluded that both species of Iuticosaurus cannot be distinguished from other titanosaurs and are therefore nomina dubia.[citation needed] It was, however, probably a titanosaur.[6]
