Introduction
I am a geologist, especially ichnologist. I am working at School of Resources and Environment, Henan Polytechnic University from 2012 to now. I am interested on the trace fossils response to the major biotic-environment event in the Phanerozoic, especially around the Permian-Triassic transition and Ediacaran-Cambrian transition. I teach Paleontology and Stratigraphy\ Sedimentology\ Ichnology in our University to bachelors and masters.

Article
Full-text available
Zoophycos is one of the most complex and enigmatic trace fossils recorded in marine strata from Cambrian to Quaternary worldwide, which is invaluable for the study of Phanerozoic development of organism-environment interactions. Here we address and demonstrate the macroevolution of Phanerozoic Zoophycos by assembling 448 points in constructing the...
Article
The Longmendong section is one of the few Early Triassic successions containing fluvial to marine deposits in South China. No trace fossils have been recorded in the fluvial deposits, but a total of 26 ichnospecies are reported from the Lower Triassic Dongchuan, Feixianguan and Jialingjiang formations in this section. This ichnofauna represents bra...
Article
Widespread oceanic anoxia has been implicated as a killing mechanism during the end-Permian mass extinction (EPME). A high-resolution investigation of pyrite framboids and bioturbation structures in the Shangsi section of South China has revealed repeated and frequent fluctuations of coupled anoxic/euxinic to dysoxic/oxic episodes in the latest Per...
Article
Changes in diversity of trace fossils through time provide information about evolutionary innovations in animal‐substrate interactions. Global ichnodiversity changes at ichnogeneric rank are useful to capture major trends, but may be insufficient to reveal minor behavioural innovations. A quantitative analysis of ichnodiversity trajectories at ichn...
Article
Dictyodora has been generally considered an ichnogenus with a restricted temporal range from the Cambrian to the Mississippian. Until now, there have been no reports of Dictyodora after the Mississippian. Here we report on well-preserved and abundant Dictyodora from deep-sea sediments of the Lopingian Maomaolong Formation in West Qinling, central C...

The Jiaguan Formation and the underlying Feitianshan Formation (Lower Cretaceous) in Sichuan Province yield multiple saurischian (theropod–sauropod) dominated ichnofaunas. To date, a moderate diversity of six theropod ichnogenera has been reported, but none of these have been identified at the ichnospecies level. Thus, many morphotypes have common...
Article
An assemblage of eubrontid-type theropod tracks, representing terrestrial progression and turtle track swim tracks representing subaqueous progression characterises a newly reported site in the Middle Jurassic Zhiluo Formation in Shaanxi Province China. While eubrontid tracks are common in the Jurassic of China, turtle swim tracks have only compara...
Article
Full-text available
Rich tetrapod ichnofaunas, known for more than a decade, from the Huangyangquan Reservoir (Wuerhe District, Karamay City, Xinjiang) have been an abundant source of some of the largest Lower Cretaceous track collections from China. They originate from inland lacustrine clastic exposures of the 581–877 m thick Tugulu Group, variously divided into fou...
Article
Multiple sauropod-track-bearing horizons occur in the Middle Jurassic Shaqiaomu Formation, in the Chaya Group of Eastern Tibet. These add to the report of a previously described sauropod trackway, which is a famous tourist attraction and became part of a folkloric legend. From an ichnological point of view, multiple track-bearing levels are consist...
Article
The carbonate rocks of the Ordovician Majiagou Formation from the northwestern part of Henan Province and their diverse trace fossils provide an outcrop analogue for bioturbated, low porosity and low permeability carbonate reservoirs. Three ichnofabrics can be defined based on the ichnotaxonomy, ichnodiversities, individual abundances and overall b...
Article
The Messinian diatomaceous deposits are widely exposed in the Lower Chelif Basin (NW-Algeria). The upper part of the Diatomaceous Formation is intercalated by four diatomaceous beds rich in Zoophycos and Chondrites. Both these traces were produced by the members of endo-benthonic fauna adapted to nutrient exploitation within sediments. In the Diato...
Article
We report the discovery of concentrated invertebrate inchnofossils in close association with a dinosaur nest from the Hekou Formation in Jiangxi Province, China. The seven dinosaurian eggs reported clearly belong to the Elongatoolithidae and burrow traces were most likely made by small crustaceans. This association prompts the question as to whethe...
Article
Large numbers of densely distributed Rhizocorallium provide a window to understanding the behavioural and functional changes of the trace maker after extreme environmental events. This study focuses on the analysis of Rhizocorallium from the Middle Triassic (Anisian) limestones in the Boyun section, Yunnan Province, Southwest China to investigate t...
Article
Slabs with tetrapod tracks from the Madigou Village quarry in the Tuchengzi Formation have famously been used as building stones at the imperial summer resort locality, also referred to in the ichnological literature as the “Chengde Summer Palace.” The Jurassic-Cretaceous boundary Tuchengzi Formation has elsewhere in the region yielded differently...
Article
The ichnogenera Zoophycos and Chondrites are described for the first time from the Middle Jurassic of Algeria. The trace fossil assemblage recovered from the Mélah Formation contains seven ichnospecies (Chondrites targionii, C. ?intricatus, Zoophycos brianteus, Z. cauda-galli, Zoophycos isp. A, Zoophycos isp. B and Zoophycos isp. C), which all repr...

Article
Trace fossils are important evidence of benthic activity and proxies of bottom and interstitial water oxygen content, making them a promising tool to understand the oceanic redox evolution and extinction patterns during the end-Permian mass extinction (EPME). Detailed bed-by-bed ichnologic studies were performed at a high-resolution scale from two...
Article
Many newly-discovered dinosaur tracksites have recently been reported from the Lower Cretaceous Dasheng Group of Shandong Province. These are proving valuable as tools for characterizing the fauna in deposits almost devoid of body fossils. Here we report on a new Cretaceous site, the 14th documented in recent years, with multiple track-bearing leve...
Article
New ichnological data from the Lower Triassic (Induan) Dongchuan Formation (Longmendong, South China) record the recovery interval of marginal-marine communities following the end-Permian mass extinction. Here, we document six ichnogenera from the upper part of the Dongchuan Formation of Dienerian (Early Triassic) age in the Longmendong area, Sichu...
Article
Full-text available
Bioturbation plays a substantial role in sediment oxygen concentration, chemical cycling, regeneration of nutrients, microbial activity, and the rate of organic matter decomposition in modern oceans. In addition, bioturbators are ecosystem engineers which promote the presence of some organisms, while precluding others. However, the impact of biotur...

Abundant and diverse trace fossils occur in the littoral-neritic sediments recording an Early Devonian transgression in South China. The well-exposed Ganxi section is located in the Longmen Mountain 100 km northwest of Chendu, Sichuan. The Lower Devonian strata are dominated by sandstones, siltstones, muddy shales, limestones, bioclastic limestones...
Article
Abundant, well-preserved Zoophycos is common in the lower and middle Permian paleotropical neritic limestone of South China and in the middle Permian glaciomarine lithic wackestone of southeastern Australia. Zoophycos from both regions is composed of a marginal tube and a tongue-like spreiten complex, the latter itself consisting of primary lamella...
Article
In this paper, we review the biotic and environmental events by examining the trace fossil records in association with the 'Big 5' mass extinctions in Phanerozoic, including the transitions of Ordovician-Silurian, Frasnian-Famennian, Permian-Triassic, Triassic-Jurassic and Cretaceous-Paleogene. The benthic fauna reflected in the trace fossil record...
Article
A Lower Devonian (Emsian) tempestite in the western Yangtze plate, China, was studied based on ichnological and stratigraphical features. The results indicated that the local tempestite can be grouped into clastic constituent types, which include bottom erosion structures, graded beds, swaley cross-stratification (SCS), parallel lamination, bioturb...
