山东莱阳晚白垩世棱柱形蛋新属种及其意义
New ootype prismatoolithids from the Late Cretaceous,Laiyang Basin and its significance
摘要
Abstract
Here we discribe a new ootypes of prismatoolithids found from the Late Cretaceous Jiangjunding Formation in the Laiyang Basin,Shandong Province.On the basis of characters such as elongate ovoids,smooth eggshell surface,relatively thinner eggshell thickness,prismatic eggshell units,slender pores in radial section of eggshell and little pores with round or irregular shapes in tangeital section of eggshell,we erect one new oogenus and one new oospecies:Laiyangoolithus lixiangensis oogen.et oosp.nov.The discovery of L.lixiangensis not only enriches the diversity and composition of the Laiyang Dinosaur Egg Fauna,but the paleogeographic distribution of primatoolithids as well.In addition,it provides more paleontological materials for the study of the diversity and paleogeographic distribution of troodontids in China.关键词
