Abstract

Crinoids from each of the five Pennsylvanian epochs are described from 26 localities in New Mexico. The crinoid faunas occupied diverse shelf environments around many intermontane basins of New Mexico during the Pennsylvanian. The crinoids described here include 29 genera, 39 named species, and at least nine unnamed species, of which one genus and 15 named species are new. This report more than doubles the number of previously known Pennsylvanian crinoid species from New Mexico; 17 of these species also occur in midcontinent faunas. New Mexico Pennsylvanian crinoids exhibit greater species richness than Pennsylvanian faunas from the intermontane basins of Colorado, Utah, and Arizona and show some generic affinity with Great Basin Pennsyl-vanian faunas. They indicate seaway connections were open, although perhaps intermit-tently, throughout the Pennsylvanian between the intermontane basins of New Mexico and midcontinent basins in Texas and Oklahoma. New taxa introduced are: Lekobikocrinus n. gen., Aaglaocrinus bowsheri n. sp., Diphuicri-nus borgesae n. sp., Goleocrinus chronici n. sp., Metacromyocrinus cedroensis n. sp., M. szaboi n. sp., Ulocrinus manzanitaensis n. sp., Mosco-vicrinus ? rotundobasis n. sp., Endelocrinus globularus n. sp., Neoprotencrinus gutschicki n. sp., Euerisocrinus tijerasensis n. sp., Apograph-iocrinus rimosus n. sp., A. kietzkei n. sp., Metaffinocrinus noblei n. sp., Sciadiocrinus ornatus n. sp., and Paramphicrinus novamexi-canus n. sp.

新墨西哥州宾夕法尼亚的菊科植物

新墨西哥州的26个地方描述了宾夕法尼亚五个时期的海百合。在宾夕法尼亚时期，在新墨西哥州的许多山间盆地周围，海红类动物占据了不同的陆架环境。本文所描述的海百合包括29属、39个已命名种和至少9个未命名种，其中1属和15个已命名种为新种。该报告将来自新墨西哥州的宾夕法尼亚菊科植物的数量增加了一倍以上;其中17种也出现在中大陆的动物群中。新墨西哥州宾夕法尼亚类海蛇科动物的物种丰富度高于科罗拉多州、犹他州和亚利桑那州的山间盆地的宾夕法尼亚类动物，并与大盆地宾夕法尼亚类动物有一定的亲缘关系。它们表明，在新墨西哥州的山间盆地和德克萨斯州和俄克拉荷马州的大陆中部盆地之间的整个宾夕法尼亚地区，海道连接是开放的，尽管可能是间歇性的。新引进的分类群有:Lekobikocrinus n. gen.、Aaglaocrinus bowsheri n. sp.、Diphuicrinus borgesae n. sp.、goeocrinus chronici n. sp.、metacroomyrinus cedroensis n. sp.、M. szaboi n. sp.、ulocrius manzanitaensis n. sp.、Moscovicrinus?圆孔线虫、球状线虫、古氏新蛋白线虫、提jeraseuisocrinus、巨斑线虫、A. kietzkei、metaffinorinus nogii、Sciadiocrinus ornatus、novamexicanus副毛虫

期刊介绍： New Mexico Geology is a quarterly, peer-reviewed journal available by subscription. Articles of original research are generally less than 10,000 words in length and pertain to the geology of New Mexico and neighboring states, primarily for an audience of professional geologists or those with an interest in the geologic story behind the landscape. The journal also publishes abstracts from regional meetings, theses, and dissertations (NM schools), descriptions of new publications, book reviews, and upcoming meetings. Research papers, short articles, and abstracts from selected back issues of New Mexico Geology are now available as free downloads in PDF format. Back issues are also available in hard copy for a nominal fee.
