A New Species of Tiaracrinus from the Latest Emsian of Morocco and Its Phylogeny
A new species of Tiaracrinus from the latest Emsian of Morocco and its phylogeny CHRISTIAN KLUG, KENNETH DE BAETS, CAROLE JUNE NAGLIK, and JOHNNY WATERS Klug, C., De Baets, K., Naglik, C.J., and Waters, J. 2014. A new species of Tiaracrinus from the latest Emsian of Morocco and its phylogeny. Acta Palaeontologica Polonica 59 (1): 135–145. We describe a new species of the unusual crinoid Tiaracrinus, T. jeanlemenni sp. nov. from the latest Emsian of the fa- mous mudmound locality Hamar Laghdad, Morocco. It differs from the previously known species in the higher number of ribs and the vaulted rib-fields, which is corroborated by the comparison of simple quantitative characters and ratios as well as by the results of a cluster analysis and a Principal Component Analysis. Based on the new material and the published specimens, we discuss the phylogeny of the genus and suggest that T. oehlerti and T. moravicus represent the ancestral forms of this small clade. Key words: Crinoidea, mudmounds, phylogeny, morphometry, symmetry, Devonian, Morocco. Christian Klug [[email protected]] and Carole J.

Dornbos, Department of Earth Sciences, University of Southern California, Los Angeles, CA 90089-0740, [email protected] ABSTRACT The broad marine ecological settings prevalent during the late Neo- proterozoic–early Phanerozoic (600–500 Ma) interval of early metazoan body plan origination strongly impacted the subsequent evolution and development of benthic metazoans. Recent work demonstrates that late Neoproterozoic seafloor sediment had well-developed microbial mats and poorly developed, vertically oriented bioturbation, thus producing fairly stable, relatively low water content substrates and a sharp water-sediment interface. Later in the Cambrian, seafloors with microbial mats became increasingly scarce in shallow-marine environments, largely due to the evolution of burrowing organisms with an increasing vertically oriented component to their bioturba- tion. The evolutionary and ecological effects of these substrate changes on Figure 1. Looping and meandering trace fossil Taphrhelminthopsis, made by a large Early Cambrian benthic metazoans, referred to as the bioturbator, on a bedding plane from Lower Cambrian Poleta Formation, White-Inyo Mountains, California.

This period also documents a major change in Evolution the nature of the sea floor: Neoproterozoic-type substrates stabilized by microbial mats were replaced by un- fl Sea oor consolidated soft substrates with a well-developed mixed layer. The effect of this transition on the ecology and Attachment evolution of benthic metazoans is termed the Cambrian Substrate Revolution (CSR), and this is thought to have impacted greatly on early suspension-feeding echinoderms in particular. According to this paradigm, most echinoderms rested directly on non-bioturbated soft substrates as sediment attachers and stickers during the Cambrian Epoch 2. As the substrates became increasingly disturbed by burrowing, forming a progressively thickening mixed layer, echinoderms developed new strategies for attaching to firm and hard substrates. -
