Recommended Posts

Has anyone purchased Bill Thompson's addendum to his Echinoids of Texas?  If so what did you think?

The original book has a nice variety of specimens but I hope someone was able to convince him that there were no Mellita sand dollars in the Cretaceous.

The errors in the first publication were numerous.  As a point of reference, an excerpt from the published 2019 article, On the description of new species of the Echinoidea class (Echinodermata) during the period 2014-2018. Vicent Gual i Orti, Javier Segura Navarro & Enric Forneri Valls

(Roughly Translated from Catalan)
".... Methods

The object of study has been defined, the conditions for enter the sample, all species descriptions new fossils, from all over the world, of the Echinoidea class in the period 2014 - 2018, both years included, published in scientific journals and following the rules of the International Code of Nomenclature Zoology: FIVE (ICZN, 1999). Methodologically, are excluded from the sample, on the one hand, the creation a supraspecific or infraspecific levels and, on the other hand on the other hand, new combinations or names they kill previously described species. It is also not sideren the descriptions of new taxa, the author of which disregard the rules of the FIVE (ICZN, 1999: R8A) or have not published in scientific journals. As is the case with Thompson, W. R. (2016), who a monograph describing 46 species is self-published new Texas, not subject to external reviewers and where they create species with little material, in fact two - thirds of the total (30 species) are described with a single specimen, often by subtle quantitative differences with respect to the already known Texan species; he is also vulnerable, in some cases, FIVE recommendation 25C (ICZN, 1999); for all this, this study is considered would require a thorough overhaul.  ...."

Thompson has a lengthy errata web page regarding the original publication. Mostly typos or incorrect references. I found it confusing and for many new species not clear as to what made each different.

Copy of above mentioned echinoid paper:

Has Bill Morgan who wrote the “Collector's Guide to Texas Cretaceous Echinoids” published any addendums? Did he also publish new species? If so, did he also get criticized for not following the ICZN guidelines?

He has not published addendums, nor any new species. Thus, ICZN criticism would be unwarranted.

Morgans book was also published by a science publisher.

It was noted in his errata. The source formation is in question as well. It will be interesting to see how this is resolved.
