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.
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.
On Thursday 13th, Dr. Darin Croft, PhD, a fossil mammals specialist, will give an open lecture at Mef facilities.
Dr. Croft is a Paleomammalogist (Paleontologist specialized in mammals), dedicated to study the evolution of mammals over geologic time; his research is focused mainly on the evolution of South American mammals. For most of the Cenozoic Era (the past 66 million years), South America was geographically isolated from any other continent; thus, a very odd, unique fauna developed.
These are the first remains of pterosaurs found in the Province of Chubut. The excellent state of preservation of cranial fossils reveals information about brain evolution and adaptation to flight of this particular group of flying reptiles.
Scientists in charge of this investigation unveiled a new species of pterosaur from the EarlyMiddle Jurassic of Chubut. The team have named it Allkaruen koi , from the native Tehuelche words ‘all’ for ‘brain’, ‘karuen’ for ‘ancient’, and ‘koi’ for lake; referring to the type of sediment where the fossils were found.
