Post-mortem alteration of diet-related enamel surface textures through artificial biostratinomy: A tumbling experiment using mammal teeth
2019
In the fossil record, teeth are often all that remains of a fossil organism. Dental microwear texture analysis (DMTA) is a common proxy for diet using dental wear features at the μm-scale, enabling comparative and quantitative assessments of various feeding traits in extant and extinct species. In extinct species, original diet-related dental wear features may be overprinted by post-mortem alteration including fluvial transport. Here we experimentally investigate the effects of mechanical alteration on diet-related 3D enamel surface texture (3DST) patterns of different mammal teeth. Post canine teeth of Equus sp., Capreolus capreolus and Otomys sp. are tumbled in sediment-water suspensio…
Observaciones sobre algunos criterios tafonómicos usados en la interpretación de asociaciones malacológicas fósiles.

In the present paper a revision of some taphonomic criteria commonly used in the interpretation of fossil mollusca assemblages is realized . The field work on living and death assemblages of mollusca in a shallow muddy bottom has been carried out in the coast near Denia (Alicante, Spain). Although the supposed lineal relation between specific abundance and probability of autochthony could explain the structure of part of the considered assemblages, in other a clear disagreement due to a massive incursion of youth elements in observed . By other hand, the possibility of horizontal transport not detectable by these means (anonymous alochtonic fluxes) imposes another limitation to the pretende…
