Put down roots and find the plant!: Preliminary results of root etching and its implications

Abstract

Vegetation provides direct information to interpret the environment, ecology, climate and deposit of a site. The identification of the surrounding vegetation from root marks recorded on the surface of skeletal elements is a new source of information of special interest. This article is a preliminary approach to relate root marking (i.e. taphonomic effect) recorded on bone surfaces caused by plants (i.e. taphonomic agent) through an experimental model. Distinguishing the root marks of one type of plant from marks produced by any other type of plant is an investigation that has been neglected in taphonomy. The preliminary results described here represent the starting point of this research field. This is an experimental work that is currently in progress, and further studies will include higher sample sizes and the analysis of different specimens in contact with other plants such as shrubs and trees. Our preliminary results shown here come from three different root plant types (underground, subaerial and aquatic) displaying characteristic differences that reinforce the need of extending this research and the importance of the analysis of this taphonomic modification.
