| Abstract/Notes | There are unfortunately few graptolites that have retained their original chitinous periderm;when these are preserved in rocks of suitable composition they may be isolated from the matrix, and having escaped distortion, may then be studied more or less in their original condition, and much of our knowledge concerning the structure shown by this group of fossils has, in recent years, been derived from such specimens;these, since they are preserved more or less in relief, differ greatly in appearance from the film-like fossils which are of far commoner occurrence, and which can rarely be taken at their face value, but require some degree of interpretation before identification is possible. Lapworth and Nicholson both recognized this, and it is much to be deplored that modern palaeontologists too often ignore this necessity for interpretation and take graptolites at their face value, with the result that specimens that are only views of well-known species are described as new species or varieties, and the literature of the subject is again being burdened with a number of names of no scientific value or significance. |
