New Early Jurassic thylacocephalan assemblage from the Western Carpathians in Slovakia Open
Thylacocephalans (Euarthropoda: Pancrustacea) are extinct marine pancrustaceans characterised by a folded shield, with fossils known from the Upper Ordovician to the Upper Cretaceous, reaching a diversity peak in the Triassic. We described…
