报告题目：

Romundina（盾皮鱼类）与有颌类面部的起源

The Placoderm Romundina and the Origin of the Gnathostome Face

内容简介：

Romundina stellina ？rvig 1975 是在加拿大威尔士王子岛发现的一种棘胸类盾皮鱼。运用同步辐射扫描对其正型标本进行的再研究揭示了其精密的头部结构，对追溯有颌类头面部重要特征的起源具有意义。

Romundina is an acanthothoracid placoderm found in Prince of Wales Island, Canada. The re-study of the holotype specimen using SR-CT reveals its exquisitely preserved inner structures, which hold significant meaning on the study of the origin of gnathostomes facial characters.
