Palaeodiversity and evolution of selected Phoridae from Cretaceous to Holocene through different amber and copal deposits

自白垩纪以来，苍蝇(蝇科：双翅目)的辐射范围很广，从那时起就没有停止过进化。它们属于双翅目中最多样化的家族之一。在黎巴嫩、加拿大、新泽西、西班牙、法国和缅甸著名的琥珀矿床中，可以广泛地看到该群在白垩纪期间多样化的演化史。琥珀是特别有利的，因为在白垩纪和全新世之间的每个地质时代都可以观察到非常详细的形态特征。本项目旨在用选定的丰富分类群研究：1)在白垩纪期间是否已经存在磷灰石的高度形态多样性；2)在琥珀矿床覆盖的早期地质时期，该科在白垩纪之后是如何发展的；3)在保存在琥珀和COPAL中的标本中观察到的多样性是对不同时期演变的压力(例如，气候和生物变化)的反应，还是反映了不同琥珀矿床之间不可比较的数据的挖掘偏差。

The scuttle flies (Phoridae: Diptera) have radiated extensively since the Cretaceous and have never stopped evolving since then. They belong to one of the most diverse families among the Diptera. The evolutionary history of the group as it diversified during the Cretaceous period can be discerned extensively in the well-known amber deposits in Lebanon, Canada, New Jersey, Spain, France and Myanmar. Amber is particularly favourable because morphological characters can be observed in it with exceptional detail in each of the geological ages between the Cretaceous and the Holocene periods. The present project aims to study with selected abundant taxa: 1) If the high morphological diversity of phorids were already present during the Cretaceous period; 2) How the family developed after Cretaceous in the earlier geological periods covered by amber deposits; 3) If the diversity observable in the specimens preserved in amber and copal, are a response of the evolving pressures (e.g., climatic and biological changes) during the different periods or a reflection of the taphonomic bias of no-comparable data between the different amber deposits.
