The study of the evolution of living beings is a really interesting matter, because from time to time, experts discover some very revealing elements illustrating the key junctions in the development of living beings. Today, a team of paleontologists from Yale University, under the leadership of Javier Lucca, presented the results of their analysis of a new find, which could in theory shed light on quite a few hidden sides in the evolution of crustaceans. The fact is that the team of paleontologists found well-preserved remains of ancient marine creatures, very reminiscent of modern crabs.
We are talking about the discoveries on the territory of the rocky zones in Colombia and in the USA, where experts found dozens of well-preserved remains of a crustacean species unknown to science, which, judging by preliminary paleontological analysis, lived on Earth about 95 million years ago, approximately in the middle of the Cretaceous . As for the remains and the species themselves, it was qualified by scientists as Callichimaera perplexa and it represents small crustaceans with a short open tail, huge eyes without eye sockets and a larva-like body – in comparison with modern species of sea and ocean crabs.
Based on the analysis, the experts put forward the theory that this ancient species of crab was only one of the branches of the evolution of the entire species, possibly giving birth to modern crustaceans – since this is evident from the peculiarities of the formation of its ridge and shell, more reminiscent of young modern crabs did not have time to finally form the armored protective area of his body.
Whatever it was, and the discovery aroused many fans of modern paleontology and fans of the evolution of crustaceans — other groups of scientists immediately noticed the study, who noticed that, most likely, preliminary analyzes of the Yale group could be filled with errors. We only have to wait patiently for the results of the final research and hope that this ancient species of crab will really help to answer some questions.
