Pecopteris sp. Fossil
Pecopteris sp. – This name refers to a broad group of ferns belonging to the order of true ferns. These fossils are often found in large concentrations, preserved within slates formed by the deposition of fallen leaves mixed with clays, which over millions of years compressed and solidified. This high-quality specimen dates back to the Paleozoic Period (approximately 360 million years ago) and originates from the renowned Serra de Valongo in Portugal.
