The dinosaur new species discovered in Mexico

Before the meteorite changed everything about 65 million years ago, life had already made many paths in different ways and we are still discovering species from that time (thinking we don’t know all of the current ones either, that makes sense). The latter has been discovered by Mexican researchers and apparently is something like a “talkative” dinosaur.

No, Spielberg, here you don’t have any material for a live-action ‘Jurassic Park’ after the ‘Lion King’ (no, please). By the “parlanchín” we mean the indications that this new species would be particularly talkative or talkative, as described by the pelletologists. Something derived from the bones found, very well preserved, and the anatomy explored from them.

A species that would announce its arrival with fanfare

The dinosaur new species discovered in Mexico

The statement explains that a group of paleontologists from the National Institute of Anthropology and History (INAH), the Ministry of Culture institution and the National Autonomous University of Mexico (UNAM) were able to retrieve a specimen of a herbivorous dinosaur and to study that Despite having died about 72 or 73 million years ago, it was reasonably well preserved (possibly because it was covered with sediment relatively quickly, forming a kind of natural sarcophagus). After thorough study, the conclusion is that they are detecting new species: the Tlatolophus galorum.

If you’re somewhat aware of the species we usually see in dinosaur books, toys, and movies, the name might sound a bit, especially the end of the genus (Tlatolophus). “Lophus” means Latin comb, hence part of the name of parasaurolophus, mainstream herbivorous saurio wherever there is, and in this case a comb was also seen.

However, as they explain, the nose and crest, while similar to those of parasaurolofinos, did not match the shapes and proportions of a Parasaurolophus. While that of a tubular Parasaurolophus, the T. galorum is teardrop-shaped, although it has been described as a dinosaur of this Upper Cretaceous tribe.

They even started to think that this belonged to the pelvis, but eventually they saw it belonged to the skull. This apex (measures 1.32 meters, eye there) was found with other cranial bones such as the palate, the jaws and even what forms the cavity to house the brain (neurosanthronic). What paleontologists say is about 80% of the skull.

In this way, comparing to other dinosaurs in the group was a bit easier, as regarding Velafrons coahuilensis (another hadrosaur found in the region, with a more compact and non-tubular crest like Parasaurolophus) there were differences in the crest. and nose, bringing it closer to the parasaurolofin strain. But as we said, it didn’t fit into an already known one either, so they concluded it was a new genus of crested dinosaur.

Previous studies already assign communicative functions to this comb through its internal channels and connections to the nose, describing it as an “integrated trumpet”. Angel Alejandro Ramírez Velasco, doctoral student at UNAM’s Institute of Geology, goes on to explain that they know they had ears with the ability to receive low-frequency sounds, so “must have been peaceful dinosaurs, but talkers.” It suits them that they were colorful, as the illustrations show, because of the theories underlying the fact that they would emit loud noises to scare off carnivores or for reproduction purposes.

It all started with a tail

So the name of the new generation stems precisely from the allusion to this supposed speaking ability and to the summit, as we have said. The first part of Tlatolophus comes from the Nahua tlahtolli voice (word), so literally the translation is “peak word”. The species, galorum, comes from a tribute to two actors: “go” by the philanthropist Jesús Garza Arocha and “lorum” for the recognition of the support received by the López family, who collaborated with shelter, food and other facilities for the team. of paleontologists.

Regarding the discovery, Ramirez explains that they basically didn’t expect to find traces of the top of the animal, and it was a surprise to start finding bones like the scapula or femur. It was based on the discovery of a hadrosaurus articulated tail in General Cepeda, Coahuila, Mexico, prioritizing the rigorous extract of the skeleton to prevent the erosion that would continue to suffer from wind, rain, and other agents.

Researchers take the opportunity to highlight the exceptionalness of the finding (due to conservation conditions) and the importance of being notified as soon as possible if found with a possible fossil so that it can be studied by avoiding as much that it wears out. out (and especially try not to extract, nuance).

After all, it is no longer just that new species can be discovered, it is that we are still aware of the already known or the circumstances of the moment (or the relationships between the species). It can store the contents of the stomach, which gives clues about the food and even its physiology, although it is also true that fossils can sometimes be found in a drawer.
