四川盆地恐龙足迹化石研究综述

A review of dinosaur footprints in Sichuan Basin

四川盆地的中生代陆相地层十分发育,盛产恐龙化石和恐龙足迹化石。自20世纪40年代在四川广元首次发现恐龙足迹化石以来,迄今四川盆地已命名的恐龙足迹化石共20属24种,超过中国现已发现的恐龙足迹化石种类(39属55种)的2/5,成为中国发现恐龙足迹化石种类最多的地区。四川盆地恐龙足迹化石具有时代最早、分布广泛、种类众多的特点。建议今后重点加强晚三叠世恐龙足迹化石的研究,深入开展早侏罗世恐龙足迹化石的研究。

Since the first discovery of footprints in Guangyuan of Sichuan Province in 1943, more than 15 localities of dinosaur foot- prints have been found in Sichuan Basin. Up to now, 20 genera and 24 species of dinosaur footprints were named in Sichuan Basin. The dinosaur footprints from Sichuan Basin were rich, widely distributed and well preserved, in which Pengxianpus clfengensis of Late Triassic from Pengxian County, Sichuan Province was the earliest dinosaur footprint in China and it was of very important academic val- ue in studying the evolution, distribution, living habits of dinosaurs in Sichuan Basin and even in China. The geological periods from Late Triassic to Early Jurassic were the very important periods in the origin and evolution of dinosaurs in China. The study of the dino- saur footprints during Late Triassic and Early Jurassic from Sichuan Basin in the future should be enhanced.
