南极恐龙的种类、分布及其与冈瓦纳大陆演化的关系
The species and distribution of dinosaur fossils in Antarctica and their rela-tionship with the evolution of Gondwana
摘要
Abstract
Dinosaurs serve as excellent indicators in the study of the remarkable evolution of life.Their fossils are widely used for intercontinental stratigraphic correlation,providing crucial evidence for continental drift.In Antarctica,dinosaur fossils are mainly found in the continental sediments from the Beardmore Glacier area of the central Transantarctic Mountains and the marine sediments from James Ross Island in the Antarctic Peninsula.This paper presents a systematic summary of the species,distribution,and exposure of dinosaur fossils in Antarctica and examines the links between these dinosaurs and the evolution of Gondwana:(1)the dinosaurs found in the Beardmore Glacier area may have lived in the Early Jurassic under a seasonal dry climate in the river areas in the back-arc foreland basin;this corresponds to the initial break-up of Gond-wanaland.(2)The dinosaurs found around James Ross Island lived in the Late Cretaceous under a warm and humid climate and were in a shallow-water delta in a backarc basin;this corresponds to the latter period of Gondwanaland during which the land masses separated completely.关键词
