Drepanaspis (from Greek: δρεπάνηdrepánē 'sickle' and Greek: ἀσπίςaspís 'shield') is an extinct genus of primitive jawless Ostracoderms from the Early Devonian (approximately 416 - 397 mya) that belonged to the phylum Chordata, infraphylum Agnatha, class Pteraspidomorphi, and the subclass Heterostraci.[1]Drepanaspis are assumed to have lived primarily in marine environments and is most commonly characterized by their ray-like, heavily armored bodies, along with their lack of paired fins and jaws.[2][3]
