Although artificially reconstructing dinosaurs fed by hunting each other is an extraordinary way of portraying the behavior of these magnificent creatures in real life, it is surprisingly rare in direct evidence of dinosaur-nutrient interaction in the fossil record.
In modern ecosystems it is fairly simple to establish ecological interactions between hunter, hunter and plant, it is enough to look at who's who or what they eat. However, since such animals have died millions of years ago, it is extremely difficult to find such interactions in the fossil record
In some cases, however, it is also possible to find extraordinary signs of eating habits from dinosaurs who have lost their lives during a deadly duel by looking at fossilized feces and knowing what a dinosaur has eaten in his life
The fossil record is pre-emptive of digested food remains, which, although rare, have been preserved in dinosaur intestines for millions of years. These trace fossils, called colloids, provide an inviting window on the real life behavior of these mysterious animals, predicting what dinosaurs are exactly at the time of death
A discovery made in past history shows that your last meal in Patagonia is still in your gut, which is a fossilized dinosaur of the Jurassic period!
The discovery comes from a class of dinosaurs called Ornithischia-Bird Hippos, belonging to a new dinosaur species called Isaberrysaura mollensis. It is known that this dinosaur species, reaching 5-6 meters in length, lived in the early Jurassic period and nowadays in the deltas of Argentina's Neuquén state.
Although this new type of dinosaur discovered is apparently similar to the Stegosaurus, extensive anatomical analysis of the remains showed that the latter is more associated with early ancestors of dinosaurs such as Iguanodon and Hysilophodon.
The special thing at this point is that the dinosaur has survived for 180 million years, where the last meal you've eaten is already rotting and your gut filled it for some time. Isaberrysaura name given to this species, in honor of Isabel Valdivia Berry, who underwent the discovery for the first time in the literature in 2009.
It is stated that the seeds found among the food residues are fossilized, that is, they stay in mineral depressions and become hardened and protected for millions of years. It is reported that some of the seeds remain untouched, which means that this little gluttonous dinosaur discovered has been wiped away with impatience at the place where it swallowed its last meal. It is likely that these hardened seeds, the last dinosaur meal, had passed through the digestive organs of dinosaurs and then thrown out of the body as seed nubs, which means that the seeds could still be germinated at that time.
