When I think sauropod, I think of North America's Jurassic giants. That's probably because these dinosaurs - Diplodocus, Supersaurus, Brachiosaurus, Apatosaurus, and more - historically lucked out in getting better press and more attention than all their other relatives. There's much more to the sauropod story than the hefty herbivores excavated from the deserts of the four corners, of course. Paleontologists have been finding and naming new sauropod dinosaurs at a relentless pace, and the latest comes from the approximately 72 million year old rock of central Spain.

Paleontologist V. Díez Díaz and colleagues have named the dinosaur Lohuecotitan pandafilandi. This huge herbivore was one of the titanosaurs, a specific lineage of sauropod that spread the world over during the Cretaceous, and the collection of vertebrae, hip bones, and limb elements makes Lohuecotitan the most complete titanosaur yet discovered from the Late Cretaceous of Europe.

Back in the time of Lohuecotitan, central Spain was very different. The dinosaur trod a muddy floodplain that sat closer to the coast of the ancient Ibero-Armorican Island that formed part of an ancient European archipelago, Díez Díaz and coauthors write. Other big sauropods called this island chain home around the same time, such as Ampelosaurus and Atsinganosaurus from France, but precisely how these dinosaurs relate to each other - and how many sauropod species there were in these habitats - is unknown. Lohuecotitan is another piece to the prehistoric puzzle, holding the promise of more out there waiting for a paleontologist to have a lucky day.
