Scientific papers
There are so many scientific papers on ichthyosaurs. Rather than listing
all of them on this page, here
is a file containing an Endnote3.0 library for the ichthyosaurian
literature (120 kb, zipped). You will find 870 entries in the file, but
there must be some duplicate listings that I failed to delete, decreasing
the actual number. The list is by no means exhaustive, and you should
check for the latest publications yourself. Also, I am unable to provide
photocopies of the listed articles.
