Losillasaurus (meaning "
neural spine of the proximal caudal vertebrae.[1][2] The humerus is 143 centimetres (56 in) long,[3] which despite being from a subadult specimen is within 20% of the size of Paralititan.[4] The size estimation proposed by Francisco Gascó in his master thesis is 15–18 m (49–59 ft) and 12-15 tons.[5]
Description
Several specimens of L. gianteus were described in 2019 and 2020 - one such specimen (SHN 180) consists of a single anterior caudal vertebra, while another (the holotype) consists of a partial skull with teeth and partial postcranial skeleton.[6] According to Rafael Royo-Torres et al., the specimen helps scientists to understand tooth variation, allows the positioning of isolated heart-shaped teeth in the skull and demonstrates heterodonty in Turiasauria.[7]
