Describer
Casanovas, Santafe & Sanz 2001
Time
Jurassic Late Cretaceous Early
Classification
Saurischia Sauropodomorpha Sauropoda Turiasauria
Diet
Herbivore
Fossilsite
Arenas y arcillas del Collado Formation, La Cañada (Barranco de Escaiz, Losilla. Aras de Alpuente, Valencia) Spain
Length
27.4 meter
Info
Genus - Typespecies
Based on a cranial fragment, several vertebral fragments and complete cervical, dorsal, sacrae, and caudal vertebrae; appendicular skeleton (humerus, ulna, radius, metacarpal); sternal plates; and pelvic elements (ilium, ischium and pubis).
The diagnosis of L. giganteus is based on two autapomorphies and singular combination of synapomorphies. The two autapomorphies are: neural spine of the anterior caudal vertebrae with a lateral enarded outline in dorsal view (cutlass-like shape). Moreover, the value of the relationships between the anterior-posterior dimension of the neuroapophyseal base with respect to the total highness is around 0,5\\\" The holotype is a complete anterior caudal vertebra, with a total height (centrum + neural arch) of 72 cm. The humerus length is 143 cm.

Abstract
The Late Jurassic-Early Cretaceous site of La Cañada (Barranco de Escáiz, Losilla, Aras de Alpuente, Valencia) has delivered several pieces of a new Sauropod dinosaur called Losillasaurus giganteus. The material includes a cranial fragment, several vertebral fragments and complete cervical, dorsal, sacral and caudal vertebrae; appendicular skeleton (humerus, ulna, radius, metacarpal); sternal plates; and pelvic elements (ilium, ischium and pubis).
The diagnosis of Losillasaurus giganteus is based on two autapomorphies and singular combination of synapomorphies. The two autapomorphies are: neural spine of the proximal caudal vertebrae with a laterally bowed outline in dorsal view (cutlass-like shape). Moreover, the ratio of the proximodistal dimension of the neural spine to the total height is around 0.5.
Introduction
The first knowledge we have of the existence of dinosaur remains from the Alto Turia area is due to Professor Beltrán, who, in 1920, during a meeting of the Real Academia de Historia Natural held in Valencia, discussed some fossils recovered in Benageber by a teacher from the town, highlighting among them “a tooth and a vertebra of Iguanodon,” as well as a tooth of “an apparently new species of reptile.” In 1925, Professor Royo y Gómez cited the importance of a shipment of fossils from Professor Beltrán for his research.
Among them he noted diverse remains of reptiles recovered from Benageber (Valencia) including a tooth fragment of a sauropod dinosaur, certainly the same one mentioned by Professor Beltrán as a tooth of “a (new) species of reptile” – plus two femoral heads of Megalosaurus and an assortment of dinosaur vertebrae. At the XIV Congreso Geológico Internacional, Professor Royo y Gómez presented a communication that emphasized the important discoveries of dinosaurs and other vertebrates that had occurred in the preceding ten years in the purported continental Spanish Lower Cretaceous.
On page 2040 of his review (1926a), he specified that it was between 1916 and 1919 that the teacher from Benageber, José Ma Catalá, who discovered the tooth fragment and vertebra that Professor Beltrán (1920) mentioned during a regular meeting of the Real Sociedad Española de Historia Natural mentioned above. Professor Beltrán indicated that he later visited Benageber and found some bone fragments that allowed him to pinpoint the position of the localities discovered previously by Catalá.
This discovery stimulated the Benageber teacher to continue searching for remains, resulting in the discovery of “a certain number of bones and vertebrae of dinosaurs.” In his synthesis on the discoveries of gigantic reptiles in Levante, Royo y Gómez (1926b) linked the discoveries of Benageber, explaining the many ups and downs of the discoveries, to specific and varied groups of dinosaurs. It was a summary of material discussed in previous works.
