Osteology and morphology of the probable stem-group osteichthyan Lophosteus superbus Pander from the Silurian of Estonia

内容简介

Lophosteus superbus是在爱沙尼亚志留纪地层中发现的早期有颌类，其已知化石材料十分零散。近年来，瑞典乌普萨拉大学Per Ahlberg团队运用多种手段对其进行详细研究，揭示了Lophosteus superbus作为硬骨鱼纲干群成员，为围绕硬骨鱼纲起源的相关古生物学问题提供的一系列重要证据。

Lophosteus superbus Pander is a probable stem-group osteichthyan from the Silurian of Estonia. It has been known to paleontologists for over 150 years. However, its scattered and fragmental nature means that only through repeated investigations, especially those done by Prof. Per Ahlberg’s group in recent years, that its significance in the origin of osteichthyan can be fully exploited. Prof. Per Ahlberg and Henning Blom will explain how these jigsaw puzzle games were played.

报告人

Per E. Ahlberg，瑞典著名古生物学家，现任乌普萨拉大学教授，瑞典皇家科学院院士。Per Ahlberg致力于早期脊椎动物的古生物学证据，以及大进化型式和分子发育机制调控之间关系的研究，已获得多项突出成就。

Prof. Per E. Ahlberg is currently a professor at the University of Uppsala. He was also elected to the Royal Swedish Academy of Sciences. His principal fields of research are the Palaeozoic vertebrate evolution with focus on the origin of tetrapods, and the relationship of molecular-developmental patterning to morphological evolution.

 Henning Blom，乌普萨拉大学高级讲师，致力于围绕早期脊椎动物三大演化事件，即颌起源、有颌类冠群起源以及四足动物起源展开的古组织学和比较解剖学研究。

Henning Blom is currently a senior lecturer at the University of Uppsala. His main research activities are built around the framework of using fossil data to describe and understand the evolutionary history of early vertebrates in general, and in particular the origin and early evolution of gnathostomes, crown-group gnathostomes and tetrapods.
