5 Euros Lourinhanosaurus antunesi, Silver

Lourinhanosaurus antunesi is a theropod dinosaur known exclusively from a single juvenile specimen unearthed in 1982 near Lourinhã, on Portugal's Estremadura coast — a region that has yielded some of the most significant Late Jurassic fossil material in Europe. The Lourinhã Formation, deposited roughly 150 million years ago, sits in a geological window that has produced multiple species found nowhere else, making Portugal a quietly important address in vertebrate paleontology.

This coin is part of INCM's ongoing Portuguese Dinosaurs series, which began drawing international collector attention for its scientific specificity rather than the usual broad treatment of prehistory.
