Comment on “Palaeoenvironmental control on distribution of crinoids in the Bathonian (Middle Jurassic) of England and France” by Aaron W. Hunter and Charlie J. Underwood
Aaron W. Hunter and Charlie J. Underwood in their article published in Acta Palaeontologica Polonica (Hunter and Underwood 2009) present some interesting results regarding facies control on the distribution of certain crinoids in the Bathonian of England and France. This is an important contribution, but we feel necessary to comment on some issues raised in their paper.
