Spain’s Mesozoic strata—especially those in Aragón—have yielded hundreds of skeletal remains, eggs, coprolites, and spectacular trackways (over 200 ichnite sites nationwide). Below is an expanded English adaptation of key finds, perfect for palaeo-enthusiast readers.
Group: Theropoda (bipedal carnivore)
Size: ~6 m long
Spanish record: Tooth from Mora de Rubielos, Teruel (Aragón)
Notes: Robust tail balanced the torso; preyed on smaller dinosaurs and scavenged carcasses.
Group: Sauropoda (herbivore)
Size: 18 m long; 11 t
Habitat: Open woodlands and lowland plains across Iberia
Status: One of the smaller “whale lizards.”
Group: Basal macronarian sauropod
Locality: Galve (Teruel) near the ancient Tethys shore
Traits: Spatulate, furrowed teeth; excellent skeletal completeness makes it a Spanish reference taxon.
Biogeography: Sister material in the Americas hints at former continental links.
Group: Carcharodontosaurian theropod
Locality: Las Hoyas, Cuenca
Age/Size: 130 Ma; ~6 m long
Signature feature: Two tall, triangular neural spines (“hump/crest”) on the back.
Group: Titanosauriform Sauropoda
Locality: Peñarroya de Tastavins, Teruel
Size: 17 m; 20 t
Age: 125 Ma
Sites: Teruel, Castellón, Cuenca, Soria, La Rioja, etc.
Size: 10 m; 4–5 t
Adaptations: Prehensile digits; facultative biped/quadruped.
Record: Single tooth (Las Zabacheras, Galve)
Profile: 2 m, fleet-footed herbivore with a beaked snout—avian precursor traits.
Evidence: Dorsal spine from Galve
Hallmarks: Back plates, spiked tail (thagomizer), low-slung quadruped stance.
Finds: Tooth (Piélago) and tracks (Corrales de Pelejón, Galve)
Features: Feathers, sickle claw, active predation.
Sites: La Cantalera (Josa) and Vallipón (Castellote)
Signature: Crocodile-like snout, fish-eating teeth, two-fingered forelimbs.
Material: Teeth from Galve
Stats: 8 m, 10 t; long neck, slightly elongated forelimbs, pleurocoelous (hollow) vertebrae.
Specimen: Femur (Cerrada Roya–Mina, Teruel)
Range: Also known from England
Size/Mode: 5 m long, 1.2 m tall herbivore.
Find: Tooth from Galve—sharp with multiple ridges (“hedgehog tooth”)
Ecology: 60 cm omnivore; two enlarged caniniform teeth suggest occasional predation.

Exceptional stratigraphy – Continuous Late Jurassic to Early Cretaceous fluvial and coastal deposits.
Mixing of Laurasian faunas – Iberian finds bridge European and North African lineages.
Ichnite richness – Track sites reveal social behaviour, speed estimates, and even skin impressions.
Exploring Spain’s “lost giants” not only rewrites European dino-biogeography but also inspires new fossil hunters to look beneath familiar landscapes.
