GSM = British Geological Survey TCD = Trinity College, Dublin NMINGF = National Museum of Ireland "As much of the material used in the study comes from museum collections, unknown biases may be built into the observations made [...]. This results from selective collecting in the past and leads to an over-abundance of certain taxa in the fauna [...]. It may also lead to a distorted interpretation of preservational modes and taphonomy. " (Evans, 1993). | |
