摘　　要：本文针对鹦鹉螺类与平旋壳形菊石类等水生动物鉴定中存在的问题,从外形、生长线、红褐色放射状斑纹、缝合线及脐部特征等出发,归纳总结了海关实验室鉴定的要点。现生鹦鹉螺主要依据壳口、尺寸、脐部、红褐色放射状斑纹及生长线等方面的差异进行鉴定;阔厚角石鹦鹉螺化石和平旋壳形菊石化石主要依据壳体、壳口、缝合线、脐部、生长线、隔壁及汲水线等方面的差异进行鉴定。本研究可为鉴定人员实操提供参考和借鉴。In view of the challenges in identifying aquatic animals such as Nautilidae,Eutrephoceras and Helicoceramites,this paper summarizes key identification points employed by customs laboratories,including external morphology,growth lines,reddishbrown radial markings,sutures and umbilical features.The identification of extant Nautilidae mainly relies on differences in peristoma,size,umbilical part,reddish-brown radial markings and growth lines.Eutrephoceras and Helicoceramites fossils are identified based on the differences in shell,peristoma,suture line,umbilical part,growth lines,septum and drawing line.This research can provide valuable reference for practitioners involved in the identification process.
