Type Species

Smilostylia bukovensis Roniewicz, 1966: 195, pl. 7, fig. 2a,b; Monotypy Roniewicz, 1966: 195

Type Specimen: Holotype; ZPAL H.III/118; Verified; Dry Preserved

Type Locality: Bukowa, Holy Cross Mts, Poland. Late Oxfordian-Early Kimmeridgian, Late Jurassic



Phaceloid, increase by marginal budding. Wall thick, septothecal with free ?trabecular elements; costae faintly marked on the wall surface. Symmetry bilateral; septa of two size orders well developed and the S3 septa hidden in the wall structure. Distal border exsert, internal border provided with auriculae. Columella compact and lamellar. Endotheca tabular. Microstructure: In the septa, small centers distant at xxxx µm from one another are arranged in a straight or zigzag line; in the wall, the septa are juxtaposed by short linear (?trabecular) elements.


Morphological characters of two Upper Jurassic species were described by Roniewicz 1966 (the type: see above) and Roniewicz 1976: 78, pl. 19, fig. 1, and traces of the septal and wall microstructure in pl. 19, 2a,b. Well illustrated find from the Upper Triassic named Protoheterastraea razorensis Turnšek 1991: 182, has all features of Smilostylia; it resembles Late Jurassic finds in its state of skeleton preservation.


From other phaceloid corals the genus differs in following features: in the wall structure containing ?trabecular elements, auricular septa, flat columella and tabuloid endotheca.


Three species are known.


  • Southern Europe; Late Triassic
  • Central Europe; Late Jurassic
