燕山期环太平洋构造活动导致辽西频繁地火山喷发。巨星火山灰一次次覆盖火山周围丛林和湖沼.掩埋了各种生物,形成学术价值极高的化石库(fossillagerstatte),尤其是鸟类和昆虫化石及动物的毛发、羽毛、膜翅及内脏等软组织结构,都或多或少地以精细的碳化膜或印痕保存。特别是近年一系列新发现,如孔子鸟(Confucinsornis)和带毛的秀颌龙(Compsognathus)/中华龙鸟(Sinosauroteryx)等,引起国内外学术界的轰动。笔者研究了其中一批化石,从古生态和埋藏事件进行探讨认为:(1)该生物群代表分子中鹦鹉嘴龙(Psittacosaurus)、带毛秀颌龙/中华龙鸟及孔子鸟等,很可能是温血动物。(2)频繁的火山喷发不但将巨量的火山灰沉积在广大的湖泊丛林区,加快了其沼泽化的进程,对煤层及油页岩层的形成起了催化作用。
Yanshan Period Pacific tectonic activities led to frequent volcanic eruptions in western Liaoning. Time and again volcano ash covered the jungle and lagoon around the volcano. Buried a variety of organisms, the formation of fossil library of academic value (fossillagerstatte), especially birds and fossils of insects and animal hair, feathers, wing and visceral soft tissue structures, more or less with fine carbonation Membrane or imprint preservation. In particular, a series of new discoveries in recent years, such as the Confucinsornis and the Hairy Compsognathus / Sinosauroteryx, have aroused great sensation from both domestic and foreign academic circles. The author studied one group of fossils and discussed from the paleoecology and burial events that: (1) Psittacosaurus, Psittacosaurus, Sinonovacula constricta, and Confucius, etc. represented by the biota are likely to be warm Blood animals. (2) Frequent volcanic eruptions not only deposited a huge amount of volcanic ash in the vast jungle of lakes, accelerated the process of swamping, and played a catalytic role in the formation of coal and oil shale formations.
