Echinocrinites fenestratus (Troost, 1850) cystoid fossil described in
A Critical Summary of Troost's Unpublished Manuscript on the Crinoids of Tennessee
by
Elvira Wood
1909. This cystoid was found in Brownsport limestone of Decatur County
Tennessee USA (Silurian Period). It was assigned
U.S. National Museum number 35091 and identified as a holotype.While
fossil is described on pages 8-9, no explanation as to why no
illustration was provided. It was later renamed by
Professor Charles Schuchert (1858-1942) as
Tetracystis fenestratus (1904). He published about this same specimen in
On Siluric and Devonic Cystidea and Camarocrinus and included three photographs at Plate XXXIV figures 6-8.
