Resumen

Taphonomic analyses have been conducted on the macromammal remains
found in Sedimentary Unit 7 of the lower Pleistocene Pirro 10 site of the
Pirro Nord locality in Italy. Recent field research has concentrated on
investigating the fossil content of this site and the genesis of the karst
network and its related deposits. In the present study, we distinguish
between preburial and synsedimentary (during burial) processes in order
to group the vertebrate remains into different taphonomic categories
according to their various states of preservation, thus introducing the
concept of taphorecord—borrowed from invertebrate taphonomy—into
macrovertebrate taphonomy for the first time. Element quantification,
evaluation of transport effects, and state of preservation of the skeletal
elements were studied and all elements separated into four taphorecords
according to their relative chronology. The use of taphorecords also
improves the accuracy of the data obtained from the various methods of
element quantification. The analysis of bone sorting and orientation
indicates that the fossiliferous deposits originated by water flows carrying
both fossils and sediments, alternating with phases of carcass accumulation
and reelaboration of bones from previously deposited layers. The
study presented here serves as a proof of concept for the use of
taphorecords in analyses of fossiliferous deposits in caves.
