至于古新世时代末期动物群到底发生了什么致使它们灭绝，有证据指出这是海洋的一个惊涛骇浪所散发出的大量甲烷气体所致使的，而并没有提到所谓的偏轨行星。

We compared three competing hypotheses which maintained that euprimates originated in Africa, the India subcontinent, or East Asia. Combined the recent achievements on the mammalian fauna exchanges during early Eocene between Europe and Africa, Europe and Asia, and Asia and India subcontinent, the paleogeographic models of around Turgai Strait, the new dating results of the collision between Indian subcontinent and Asia, and the phylogenetic analysis of euprimate, we suggested that the Asian-origin hypothesis of euprimates are more reliable.

全面对比了真灵长类动物亚洲起源说、非洲起源说和印度次大陆起源说，结合前人有关欧洲与非洲之间、欧洲与亚洲之间、亚洲与印度次大陆之间早始新世时的动物群交流的研究，以及有关图尔盖海峡古地理、印度板块与欧亚板块碰撞时间的研究成果，在真灵长类动物分支系统分析的基础上，提出真灵长类动物亚洲起源说是目前获得支持证据最多的假说。

综合分析得出了井研马门溪龙动物群出现于晚侏罗世早期、而且在形态组合上是较为原始的类群，形态学的鉴定和地层学结果相互吻合，同时也进一步清晰了马门溪龙属在晚侏罗世的演化脉络。

They include a survival phase, a recovery phase (middle-late Turonian) and a radiation phase (Coniacian-Santonian).

从Turonian早期至Santonian晚期，有孔虫动物群的复苏过程经历了三个时期：残存期、复苏期及辐射期，其复苏的型式为渐变式复苏。

The faunas in the two quarries are similar, but with differences in the relative abundance of some of the organisms.

该动物群中的两个采石场是类似的，但不同的相对丰度的一些生物体。
