Magnamanus grew and lived near the Golmayo Marshes during the Cretaceous Period, about 130 million years ago. Magnamanus soriaensis was a four-legged herbivore that measured at least 10 metres in length and weighed 3.5 tonnes. The specimen is one of the most complete of a dinosaur from what is now Spain’s Lower Cretaceous period.
Magnamanus looks and is the same size as Iguanodon, but it is a younger cousin that lived at least 20 million years before Iguanodon. In addition to Magnamanus, a sauropod more than 20 metres long and an armoured herbivore with massive skin plates and spikes comparable to Polacanthus were discovered in the Golmayo Formation. The Magnamanus’ jaws were filled with a vast number of old and decaying teeth. As a result, the discovery is most likely a very old animal that died in a flood and washed up on the spot.
