New sauropod dinosaur from the Lower Cretaceous of Morella (Spain) provides new insights on the evolutionary history of Iberian somphospondylan titanosauriforms.

This article focuses on the discovery and detailed description of a new somphospondylan titanosauriform dinosaur, *Garumbatitan morellensis* gen. et sp. nov., from the late Barremian Arcillas de Morella Formation in Morella, Spain. Diagnosed by a unique combination of 19 anatomical features, including distinctive femoral, tarsal, and pedal morphologies such as the absence of the calcaneum and a reduced ungual in digit III, *Garumbatitan* is recovered through phylogenetic analyses as an early-branching member of Somphospondyli within Titanosauriformes. The study highlights its differences from other Iberian Early Cretaceous sauropods, such as *Tastavinsaurus sanzi*, and discusses its implications for understanding the evolution of somphospondylan novelties and the complex phylogenetic mosaic of Iberian sauropod faunas, which include taxa with both Laurasian and Gondwanan affinities. The findings also support hypotheses of faunal exchanges during the Early Cretaceous among Europe, North America, East Asia, and Africa.
