Text-fig. 11. Eospondylus cf. primigenius (STÜRTZ) "Prastav" quarry at Praha-Holyně, Třebotov Limestone, Lower Devonian, Dalejan, NM L 36905, x 65. Overlay of proximal and distal articulations. Upper photo is proximal surface with distal bird-like articulation knobs superposed in ink. Lower photo is distal surface with proximal articulation knobs superposed in ink. The architecture of articulation surfaces is both zygospondylous and auluroid. This architecture occurs also in vertebrae of Furcaster and indicates that families Eospondylidae and Furcasteridae are closely related. in Isolated Ossicles Of The Family Eospondylidae Spencer Wright, 1966, In The Lower Devonian Of Bohemia (Czech Republic) And Correction Of The Systematic Position Of Eospondylid Brittlestars (Echinodermata: Ophiuroidea: Oegophiurida)

Hunsrück Slate articulated specimen. Underside of arm showing two contrasting appearances of lateral arm plates in a single arm. The arm is rolled slightly.

Text-fig. 6. Eospondylus primigenius (STÜRTZ) Bundenbach, Eschenbach-Bocksberg quarry, Lower Devonian, Lower Emsian (Zlichovian), Hunsrück Slate, NM S 4766, x 12.5. Undersurface of arm segments in Hunsrück Slate articulated specimen. A few lateral plates are displaced and expose details of vertebrae. The canal for radial water vessel is in center of zygosphene knob and zygotreme pit, like spout and funnel. At distal outer edges of vertebrae is cupola for tube feet. There are no under arm plates. in Isolated Ossicles Of The Family Eospondylidae Spencer Wright, 1966, In The Lower Devonian Of Bohemia (Czech Republic) And Correction Of The Systematic Position Of Eospondylid Brittlestars (Echinodermata: Ophiuroidea: Oegophiurida)

Text-fig. 2. Eospondylus primigenius (STÜRTZ) Bundenbach, Eschenbach-Bocksberg quarry, Lower Devonian, Lower Emsian (Zlichovian), Hunsrück Slate,, NM S 4764, x 3. Specimen with ventral arm coiling. The specimen is on its dorsum in slate with all five rays curled ventrally inward toward mouth area on underside of disk. Barely visible are tips of two jaws; slightly exposed are proximal parts of rays in oral view extending outward from disk. The location of abrupt ventral bending of rays is indicated by emergence from slate of five rays in aboral view that point inward toward buried disk. Based on ventral bending of rays and intimate association with crinoids Eospondylus has been interpreted as stratigraphic first occurrence of Order Euryalida, which contains epizoic gorgonocephalid and euryalid basket-stars of modern oceans. This status is rejected using new evidence from isolated vertebrae.
