NOTES, NEWS AND DISCOVERIES

A multidisciplinary team of researchers in the search of clues from an ancient ocean in Chubut

 

About 300 million years ago the Andes hadn´t risen yet, what allowed the current Pacific Ocean cover a great part of West Patagonia. The Sierra de Tepuel area, located 100 km southeast from Esquel city (West of Chubut) is especially rich in fossils from that time, which represents part of the Carboniferous and Permian Periods and has a marine record spanning a continuous temporal interval of practically 70 millions of years. This uninterrupted record of so many millions of years, along with the great amount and diversity of fossils found make this site of great importance for researchers who study this particular time lapse.

A lifelike, lifesize reconstruction of the giant dinosaur will be built in Trelew

 

This recreation will be inaugurated on February 24th; it´s the largest dinosaur known worldwide until today.

 

Scientists have been studying this new species of a giant kind of dinosaurs since 2013, when the fossil remains of at least 7 individuals were found in Chubut Province (Patagonia, Argentina). Research focuses on understanding several facets, such as: what were they like, how and when they died, what their age was, or what their surroundings were like… And a big question that challenges imagination: What would it feel like to be aside them? Soon, we´ll be able to know the answer to this question.

Some fossils found in Chubut bring answers on the origin of the tomato’ family.

 

In Chubut Province (central Patagonia), Paleontologists found the oldest fossil record for the plants family that includes tomatoes, eggplants and peppers, among many others of great economic importance. The fossils belong to a new species of tomatillo, 52 million years old. The research on them will be published tomorrow, January 6, in Science, one of the world-wide most prestigious scientific magazines.

 

Potatoes, tomatoes, peppers and eggplants are among the most popular food around the world; we have them in sauces, fillings, with pasta, in salads, and in countless dishes. They all belong to the Solanaceae family, a group of plants of great importance that also includes chillies and cucumbers, among others.

Some fossils found in Chubut Province (Patagonia, Argentina) help know that life in the region recovered quickly after the mass extinction 66 million years ago.

 

Studies made on fossil plants found in the mentioned province gave information about how he ecosystems in the South Hemisphere recovered from that event.

 

66 million years ago a huge meteorite crashed with the Earth, where Mexico is situated today, leading to a series of events that caused a major extinction that affected around 60% of the living species, plants, insects and dinosaurs among them. But: what happened afterwards? how did the species recover from that? how fast did they recover? The results of this new research gives some answers to those questions.
