| Summary: | Family Neilonellidae Schileyko, 1989 Diagnosis. Hinge plate with taxodont teeth in two series, sometimes separated by narrow, plain area, without resilifer; ligament predominantly external, opisthodetic to amphidetic, weak. Remarks. The Neilonellidae are very similar to the Nuculanidae, but the lack of a resilifer in mature adults supports their separation (Coan & Valentich-Scott 2012). The new specimens described herein differ from the Malletiidae in lacking conspicuous gapes, and from the Tindariidae in having a short gap in the dentition below the beaks (Di Geronimo & La Perna 1997). The family is currently known from the Jurassic to the present in all oceans, especially in deep water and soft substrates (Coan & Valentich-Scott 2012). ... : Published as part of Foster, William J., Danise, Silvia & Twitchett, Richard J., 2017, A silicified Early Triassic marine assemblage from Svalbard, pp. 851-877 in Journal of Systematic Palaeontology 15 (10) on page 858, DOI: 10.1080/14772019.2016.1245680, http://zenodo.org/record/10883052 ... |
