摘要
大连地区碳酸盐岩分布广泛 ,裂隙溶洞发育 ,洞穴堆积物中蕴含了丰富的更新世哺乳动物化石和古文化遗物 ,在境内陆地和附近海域陆续发现了 30余处化石点。在众多的化石点中尤以古龙山遗址和大连动物群最引人注目 ,前者在同一地点内采集到 377种上万件的脊椎动物骨骼化石 ,并伴有石器、骨器、灰烬等远古人类活动的遗物 ;后者包括了 2 8种早更新世的小型哺乳动物 ,这是大连乃至东北地区的首次报导。这些事实说明了东北地区不只是仅有晚更新世的动物群 ,至少还有早更新世的大连动物群 ,即使在晚更新世 ,也不只是单一的披毛犀 -猛犸象动物群 ,还存在着具有从华北向东北过渡性质的古龙山动物群。今后工作中应注意寻找古人类及中更新世的哺乳动物化石 ,加强对全新世动物遗骨的研究。
There are more than 30 fossil sites in Dalian land and undersea nearby,where carbonate widely distributed,karst caves and fissures well developed and largely containing Pleistocene mammal fossils and ancient culture heritages Among them,Gulongshan ruin and Dalian fauna are the most outstanding From Gulongshan ruin,over 10 000 vertebra fossils of 377 species and some remote ancient men's activity heritages have been discovered In Dalian fauna there are 28 species of Early Pleistocene small mammal This is the first reported in Dalian and even in Northeast of China It indicates that in Northeast,there are not only Late Pleistocene fauna,but also Early Pleistocene fauna,and even in Late Pleistocene there is not only simple Coelodenta-Mammuthus fauna,but also Gulongshan fauna,which reprensents a transition features from North China type to Northeast China type So,it is should be paied more attention on looking for ancient men's and Mid Pleistocene mammal fossls so as to more deeply study on Holocene remains in the future
