“…The channel diameters fall within the range of crustacean burrowing channels, and the traces are consistent with the morphology of known crustacean channels (Nickell & Atkinson, 1995;Stieglitz et al, 2000;Monaco & Garassino, 2001;Carmona et al,2004) for example: burrowing shrimps (Hasiotis & Mitchell, 1993;Nickell & Atkinson, 1995;Carvalho et al, 2007). The size of the burrow-makers can be estimated from the width of the channels (Xing et al, 2013;Xing et al, 2017). The trace makers were most likely small crustaceans, a little more than 3 cm in width.…”

“…The association of the two fossils is still cannot be ruled out completely. The decaying dinosaur eggs might increase the organic content at the burial site (Xing et al, 2017), and this may well have led to an increase in local decomposers and other small arthropods in the nearby area. This might attract crustacean trace makers (Xing et al, 2017 Dal Sasso, C., Maganuco, S., & Cau, A.…”

“…The second form is the preservation of bones and traces in passive association without obvious erosion or damage to the former (Xing et al, 2013;Xing et al, 2017). Insect traces of Taotieichnus are associated with the skeleton of the prosauropod dinosaur Yunnanosaurus from the Lower Jurassic Lufeng Formation of China (Xing et al, 2013), for examples, while Middle Jurassic tetrapod burrows are preserved in association with the large sauropod Omeisaurus from the Sichuan Basin, China.…”

“…Dinosaur bones are frequently found with associated trace fossils, including those of invertebrates (Xing et al, 2013;Xing et al, 2016;Xing et al, 2017;Dal Sasso et al, 2018). These ichnofossil associations frequently offer novel paleoenvironmental clues (Xing et al, 2013;Xing et al, 2016).…”

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 whether invertebrate activity had relations with the buried eggs. This may be just an occasional case or the eggs may have organically increased the content of organic matter in soil which attracted the crustaceans.

Scarce fossil tetrapod burrows have been recorded in Cretaceous rocks, which is probably linked to the dominant equable climates that existed for most of this period. The occurrence of Cretaceous tetrapod burrows from Patagonia (Chubut Province, Argentina) dated between 118 and 115 million years ago, gives insights into their paleoecology and paleoenvironment. The rocks containing the tetrapod burrows are of pyroclastic origin and represent eolian dunes and ash-fall deposits, some reworked by fluvial currents and others showing soil development. Fossil burrow casts preserved in a paleosol are composed by a ramp with a slightly curved or straight path in plan-view and lacking bifurcation, a rounded termination with no enlargement, showing a reniform cross-section, and are assigned to the ichnospecies Reniformichnus katikatii. The strongly flattened cross-sectional shape of the burrow casts and comparison with modern lizard burrows suggest that the producers were lepidosaurs (body mass = 50–323 g). Among Cretaceous fossorial lepidosaurs from Patagonia, the best candidate is an eilenodontine sphenodontian. Sphenodontians burrowed in the fossil soils where also arthropods, earthworms and shrubby plants thrived. The rare occurrence of tetrapod burrows in Cretaceous rocks is linked to stressing conditions related to frequent arrival of volcanic ash and a semiarid seasonal climate.
