3D morphology of post mortem acrothoracican borings in Famennian heterocorals – a morphological diversification or a continuum ichnospecies?

Abstract

Trace fossils produced by the erosional activity of organisms in hard substrates (such as drilling, grinding, scratching) are referred to as borings (Wilson, 2007). In the fossil record, they are found in the skeletons of various organisms, in rocks, and in wood (e.g.
