Growth, Distributional Controls and Taphonomy of Recent Isocrinidae (Echinodermata: Crinoidea)

长柄海百合（等海百合）是生物组合的主要组成部分，在小巴哈马海岸西侧形成了富含海百合的现代沉积物。本研究将从三个方面探讨海百合的生物学特征，因为它们有助于理解古生态过程：1)茎的生长速率和沉积物的产生；2)分布控制因素：水流、温度、活的海百合组合分布与海百合对沉积物贡献的性质和数量之间的关系是什么？3)地层学：研究区富含海百合的沉积物的时空变化和地层学变化，以及如何将其应用于化石组合的重建。等红岩的化石记录可以追溯到三叠纪，这些现代组合为更好地理解古生态过程和解释古代海盆沉积提供了极好的模拟。

Stalked crinoids (Isocrinida) represent a major component of living assemblages and produce modern crinoid- rich sediments along the western flank of the Little Bahama Bank. Three aspects of stalked crinoid biology will be examined as they contributed to understanding paleoecological processes: 1) Rates of stalk growth and sediment production; 2) Distributional controls: what are the relationships between current flow, temperature, the distribution of living crinoid assemblages and the nature and amount of crinoidal contributions to sediments? and 3) Taphonomy: what are the temporal and spatial variations and taphonomic modifications of crinoid-rich sediments in the study area, and how can these be applied to the reconstruction of fossil assemblages? Isocrinids have a fossil record dating to the Triassic and these modern assemblages represent an excellent analogue for better understanding paleoecological processes and interpreting ancient crinoidal deposits.
