The spinosaurid in the background represents a potential predator that produced the fossil vomit. Around 110 million years ago, two pterosaurs the size of seagulls were flying over a river or lake and were devoured by a larger dinosaur or pterosaur. When the predator then passed through the coastal Araripe Basin region, it regurgitated the devoured pterosaur's skulls and four fish that were also consumed. First filter feeder from the region“It was very unexpected, because fossils from the Araripe region have been studied for decades and almost 30 types of pterosaurs had already been found, none of them filter feeders. When Ghilardi realised that the fossil was a pterosaur, they contacted a team of experts to examine the specimen.
