The most common fish trace fossil, however, may be the fish swimming trace Undichna Anderson, 1976, which is typified by singular or multiple sinusoidal trails on bedding surfaces(or as ridges on soles)。展开更多

Contemporaneously preserved are prolific trace fossils, which offer good opportunities to understand the palaeoecology of marine invertebrates from a fully recovered shallow marine ecosystem. Here we present a newly discovered sinuous branching burrow from the fossil-bearing unit in Member II of the Guanling Formation. Several features, including the horizontal regular sinuous nature, the branching pattern, typical H-junction, and the small wavelength/amplitude ratio of these sinuous structures within the burrow systems justify assignment of these traces as Sinusichnus sinuosus, a trace possibly produced by decapod crustaceans. Close association ofS. sinuosus with Rhizocorallium commune suggests a deposit-feeding strategy of these trace makers. The newly reported Anisian material from the Guanling Formation in Luoping represents first report of Sinusichnus from South China. The global record of Sinusichnus occurrence suggests that these burrows might have an older history than Early Middle Triassic.展开更多

From the oral presentations, posters, intra-and post-workshop field trips, and workshop discussions, a few promising aspects of ichnological study can be outlined:(1) Ichnotaxonomy is, and will be the major endeavour of ichnologists, supplying important behavioural information for palaeontological studies, and also providing reasonable, objective, and convenient taxonomical framework for further sedimentological and palaeoecological studies;(2) Ichnofabric analysis is widely applied to in-depth sedimentological, palaeoclimatical, and petroleum exploration studies, offering a wealth of biological information that cannot be properly obtained from traditional sedimentological and geochemical analyses;(3) Study of trace fossils in the context of evolutionary palaeoecology sheds light on some intriguing issues of the biological responses during certain critical periods in Earth's history;(4)Work on combining geomicrobiology and ichnology is under way;(5) Quantitative morphological characterization has become increasingly useful in grasping the finer ingredients of functional morphology.展开更多
