Galeaspida (original) (raw)
Els galeàspids (Galeaspida) són una classe extinta de peixos àgnats que van viure tant en aigua dolça com en el mar des del Silurià mitjà al Devonià inferior (430 a 370 milions d'anys enrere). Els seus fòssils s'han trobat a la Xina i el Vietnam.

The name is derived from galea, the Latin word for helmet, and refers to their massive bone shield on the head. Galeaspida lived in shallow, fresh water and marine environments during the Silurian and Devonian times (430 to 370 million years ago) in what is now Southern China, Tibet and Vietnam. Superficially, their morphology appears more similar to that of Heterostraci than Osteostraci, there being currently no evidence that the galeaspids had paired fins. A galeaspid Tujiaaspis vividus from the Silurian period of China was described in 2022 as having a precursor condition to the form of paired fins seen in Osteostraci and gnathostomes. Earlier than this, Galeaspida were already in fact regarded as being more closely related to Osteostraci, based on the closer similarity of the morphology of the braincase.
