abstract = {{Barbed bone and antler points are regularly found washed ashore on the Dutch coast. They were originally deposited in Doggerland{\textless}br{\textgreater}and they are attributed to the Mesolithic based on typology and some direct 14C datings [1] [2]. The bones, of which the barbed{\textless}br{\textgreater}points were made, have been intensively modified during manufacture, usage and post-depositional processes. Consequently, it{\textless}br{\textgreater}is impossible to derive their taxonomical identification from morphological characteristics. In our research we have analysed ten{\textless}br{\textgreater}barbed points found on the Dutch shores using mass spectrometry and collagen peptide mass fingerprinting. Here we present the{\textless}br{\textgreater}ZooMS taxonomic identifications alongside the results of 14C ages and $\delta$ 13C and $\delta$ 15N measurements.{\textless}br{\textgreater}{\mbox{$\cdot$}} The success of the proteomic analysis of nine out of ten barbed points demonstrates that a burial in marine environments{\textless}br{\textgreater}since the early Holocene has preserved sufficient unmodified collagen to allow mass spectrometry-based taxonomic identifications.{\textless}br{\textgreater}{\mbox{$\cdot$}} Seven of the analysed barbed points were produced on Cervus elaphusand/or Alces alces (indistinguishable using ZooMS){\textless}br{\textgreater}bone and antler, while two others were identified as made with Homo sapiens bone.{\textless}br{\textgreater}{\mbox{$\cdot$}} The uncalibrated 14C ages of the barbed points fall between 9.5 and 7.3 ka 14C BP.{\textless}br{\textgreater}{\mbox{$\cdot$}} The $\delta$13C and $\delta$15N values of the human bone points suggest a freshwater and/or terrestrial fauna diet, while the Cervus/Alces{\textless}br{\textgreater}bone and antler points fall within the range of other herbivores from Doggerland.{\textless}br{\textgreater}Our study confirms that large-scale application of ZooMS is needed to reveal the selection of species used for bone-tool manufacture during Prehistory. Although our sample is small, it represents a random sample from several sites spanning the entirety of{\textless}br{\textgreater}the Mesolithic. In this light we interpret the selection of Cervus/Alces and Homo sapiens bones as a non-random and intentional{\textless}br{\textgreater}choice. The use of human bone for the production of barbed points, which possibly served as weapons, indicates a previously unknown aspect of mortuary practices in Mesolithic Doggerland.}},
