I want to cite a formal work that has properly defined the term 'riblet' - as in a form or molluscan sculpture- in a paper and can't seem to find anything apart from secondary sources on the web. Does anyone know of a thorough glossary for molluscan terminology that might have this?
Hi Sarah,
I suggest to check Bucher et al. (1996) chapter 12 - Mode and Rate of Growth on ammonoids. p. 407-461 In: Ammonoid Paleobiology by Landman NH, Tanabe K, Davis RA (eds.) On page 421 he refers to growth lines, lirae and ribs...within the whole chapter he discusses a lot more...potentially he mentions your riblets.
Treatise on Invertebrate Paleontology, Vol. I (Mollusca 6), p. N69. Riblets are defined as synonym of costellae.
The Veliger vol.7; supplement:41
riblets: small or rudimentary ribs, as the longitudinal rib lets on dentaliums.
There is an excellent glossary of gastropod shell (in many cases it is applicable to other groups) published by R.N.Kilburn as an appendix to the book of South African Molluscs. I have a PDF and can send a complete reference. it just says: RIBLET: small rib
Thank you everyone, this has been a huge help. I'm particularly excited about that Veliger volume.
You can check the following paper also mentioned above: W.H. Arnold (compiler). 1965. A glossary of a thousand-and-one terms used in conchology. Veliger Vol 7 (Supplement), iii+50 pages. 155 figure.
Your question is prescient. After more than two centuries of scientific description of mollusc shells and their sculptures can it be the case that we still lack a formal ontology of descriptive terms, characters, states etc? Progress is required.
The updated illustrated glossary of bivalve terminology: 2012, The University of Kansas, Paleontological Institute, ISSN (online) 2153-4012 by Carter et al. can be downloaded at: http://www.academia.edu/5295875/Illustrated_Glossary_of_the_Bivalvia
I suggest you use:
Winifred H. Arnold. 1965. A glossary of a thousand and one terms used in conchology. The Veliger, vol 7, supplement.
