Bonitasaura (Bonitasaura salgadoi) is among one of the smallest titanosaurian dinosaurs growing 30 ft (9 m) in total length and could extend about 9.8 ft (3 m) tall, these creatures lived during the Late Cretaceous Period, 85 million years ago. It possessed a short neck unlike other sauropods species and their dorsal vertebrae had high robust neural spines pointing out strong muscular attachments, which means that these creatures were still able to browse for high up and feed on the tree canopy.

The genus name was given after the La Bonita Quarry in the year 2004 where partial sub-adult holotype remains were found and the species name B.‭ ‬salgadoi was given in the honor of Leonardo Salgado, the Argentine paleontologist. The remains which were found included a skull with lower jaw with teeth, partial vertebrae series, and limb bones. These were notable as most of the titanosaur community skulls were separated from their large bodies as they were decomposing. The lower jaw had a ridge behind the peg-like teeth covered with beak-like keratin. It is believed that a similar structure was also on the upper jaw which helped them in chopping the food.

Bonitasaura Fun Facts

What did a Bonitasaura look like?

Bonitasaura was a giant creature but when it was compared to other related to the Titanosaur community it was the fairly small-sized genus that lived during the late cretaceous period in Argentina. The sub-adult skeleton that was found indicated that the specimen still had some time to attain their maturity and could have grown much more. When compared to other Titanosaur species, Bonitasaura had a relatively short neck but had a stocky body. The dorsal vertebrae of these specimens had high and robust neural spines, and these spines suggested a strong muscular extension, helping these creatures to feed on the tree canopy.

The skull that was found had a lower jaw with teeth which was similar to a sauropod known as the diplodocid, the lower jaw consisted of the teeth towards the back and the front was a ridge.

Another name given to these species is the La Bonita Lizard, as they were found in the year 2004 from the La Bonita Quarry from the uppermost layers of the Bajo de la Carpa Formation of the Río Negro Province.

Both Apesteguía and Gallina worked on the incomplete skull of the Bonitasaura, which was only bits and pieces like an osteological puzzle. Once all the pieces were put together it was found that these creatures had a skull that was short from front to back and a square-shaped muzzle dilated to the sides. According to the original description, these dinosaurs did not possess any beak-like hadrosaur or a parrot, but they had a casing of keratin behind their teeth in the jaw.

In the year 2004, Bonitasaura was initially classified as a family member of the titanosaurian sauropod dinosaurs on the ground of their skulls being similar to the member of the diplodocid family. Later on paleontologists Sebastián Apesteguía and Pablo Gallina reclassified this species among the members that includes Rinconsauria and Lognkosauria.
