Pelanechinus
edit- ... that the shell of the extinct sea urchin Pelanechinus was composed of separate groups of fused plates which resulted in its being flexible?

Article is new enough (Dec. 9) and long enough (2373 chars), and AFAICT is free of policy issues, but does not contain an inline citation for the suggested hook. In fact, it doesn't seem to contain the hook fact per se at all -- only as an attribute of two individual species in the genus, rather than of the genus as a whole. If all species in the genus did in fact share this property, that should be stated & cited. (Hook seems OK to me otherwise.) -- Visviva (talk) 02:48, 10 December 2012 (UTC)
- This is the first article I have written about an extinct genus and have found there are certain difficulties involved. At the time that the book was written, the species P. corallina was the only member of the genus and therefore the hook is accurate and cited. In fact, the unfused plates are not specific to this genus but are present in the whole order Echinothurioida, one of the characteristics of which is a flexible test. Perhaps it would be better to use the less interesting ALT1 hook which is cited by the Seposki reference, or ALT2 would get round the problem. Cwmhiraeth (talk) 06:32, 10 December 2012 (UTC)
- ALT1 ... that the extinct sea urchin genus Pelanechinus is known only from the Jurassic?
- ALT2 ... that the shell of the extinct sea urchin Pelanechinus corallina was composed of separate groups of fused plates which resulted in its being flexible?
Needs re-review based on new ALT hooks. BlueMoonset (talk) 17:56, 24 December 2012 (UTC)
