Losillasaurus giganteus
Losillasaurus giganteusLosillasaurus was a massive turiasaurian sauropod that browsed the subtropical coastal floodplains of the ancient Iberian peninsula. Unlike more derived neosauropods, it retained primitive cranial and vertebral traits alongside distinctive neural spines on its anterior tail vertebrae. Its long neck allowed it to sweep through mid-to-high forest canopies, shearing tough Jurassic foliage with broad, spatulate teeth.
