Vertébrés siluriens du Viêt-nam central

Vertebrate remains are described from Vietnam for the first time from the Silurian (Ludlow-Pridoli boundary). They include a new placoderm, Myducosteus anmaensis nov. gen., nov. sp., which does not belong to any of the major placoderm taxa known to date, and an acanthothoracid placoderm, an acanthodian, and possibly several osteichthyans, including a form whose ornamentation recalls the sarcopterygian Youngolepis. These vertebrate remains are found in association with a rich brachiopod fauna, and the locality is situated in the north of Central Vietnam, south of the Song Ma suture, thus on the Indochina plate.
