Ichnotaxonomic analysis of trace fossil assemblages of the Upper Triassic Nayband Formation, Tabas Block, Central Iran
This study includes a thorough systematic analysis of the ichnological record in the Late Triassic siliciclastic Nayband Formation of the Tabas Block, Central Iran. A total of 48 ichnospecies representing 28 ichnogenera are identified and their preservation aspects, paleoecological aspects, producers and behavioral aspects are discussed. The ichnofauna includes Arenicolites, Asterosoma, Bergaue...
متن کاملComparing amber fossil assemblages across the Cenozoic.
To justify faunistic comparisons of ambers that differ botanically, geographically and by age, we need to determine that resins sampled uniformly. Our pluralistic approach, analysing size distributions of 671 fossilized spider species from different behavioural guilds, demonstrates that ecological information about the communities of two well-studied ambers is retained. Several lines of evidenc...
متن کاملA closer look at the "Protopithecus" fossil assemblages: new genus and species from Bahia, Brazil.
The recently extinct large-bodied New World monkey Protopithecus brasiliensis Lund 1836 was named based on a distal humerus and proximal femur found in the Lagoa Santa cave system in the southeastern Brazilian state of Minas Gerais. These bones are from an animal about twice the size of the largest extant platyrrhines. One hundred and seventy-five years later, a nearly complete skeleton was dis...
متن کاملBehavioural variants of the trace fossil Gyrochorte
The trace fossil Gyrochorte is common in Upper Jurassic siliciclastic rocks of the Kachchh Basin, western India. In the Kimmeridgian Katrol Formation, Gyrochorte comosa Heer, 1865 is tied to storm-generated fine-grained sandstones and exhibits an internal structure composed of double arches in cross-section, confirming the three-dimensional nature of the trace fossil and its interpretation as p...
متن کاملFossilized bioelectric wire – the trace fossil Trichichnus
The trace fossil Trichichnus is proposed as an indicator of fossil bioelectric bacterial activity at the oxic-anoxic interface zone of marine sediments. This fulfils the idea that such processes, commonly found in the modern realm, should be also present in the geological past. Trichichnus is an exceptional trace fossil due to its very thin diameter (mostly less than 1 mm) and common pyritic fi...
