Wrzołek Tomasz, 2002: Siphonophrentidae (Rugosa) in the Devonian of Poland. Coral Research Bulletin 7, 229–240, Dresden.
    Four species of the family Siphonophrentidae Merriam 1974 are described from the Holy Cross Mts, Poland. The two species, Enallophrentis corniformis (Gürich 1896), and Enallophrentis polonica (Sobolev 1904) are revised, although their type material is missing; the two species described as new are Siphonophrentis laskowae sp. n. and Siphonophrentis georgii sp. n. The corals studied were possibly of the Eastern Americas origin, introduced into the Old World biogeographic Realm. During the Givetian they inhabited the fore-reef setting of the Holy Cross area. Both Eifelian and Frasnian records of Siphonophrentidae in Poland are taxonomically dubious. [original abstract]

Wrzołek Tomasz, 1993: Rugose corals from the Devonian Kowala Formation of the Holy Cross Mountains. Acta Palaeontologica Polonica 37(2–4), 217–254, Warszawa.
    Rugose corals of the Givetian to Lower Frasnian Kowala limestone Formation in the environs of Chęciny, SW Holy Cross Mts, and its age equivalents in the Silesian-Cracow region of Southern Poland represent five distinct assemblages of restricted time-and-space distribution. Within the Stringocephalus Beds the high diversity Pseudohexagonaria(?) laxa assemblage indicates open-shelf conditions whereas low diversity Temnophyllum occidentale assemblage represents restricted conditions. The transgressive Jaźwica Mbr. Locally contains diversified and cosmopolitan Acanthophyllum sp. n. fauna. Following temporally coral assemblages, i.e. Disphyllum (lower Sitkówka and Chęciny Beds) and Macgeea-Thamnophyllum (Kadzielnia Mbr., upper Sitkówka Beds) are mostly biostromes of branching corals of low taxonomical diversity typical for restricted relatively setting, rather unfavorable for rugosans. Exceptional are two Hexagonaria horizons with common massive colonies. Diffusolasma gen. nov., Sociophyllum severiacum sp. nov., Temnophyllum zamkowae sp. nov. and Hexagonaria hexagona kowalae subsp. nov. are proposed as the new taxa. [original abstract]

Wrzołek Tomasz, 1993: Reconstruction of the distal cone in the Devonian heterocoral Oligophylloides. Courier Forschungs-Institut Senckenberg 164, 179–183, Frankfurt-am-Main.
    The reconstruction of the distal cone in the Famennian heterocoral Oligophylloides pachythecus Różkowska from the Holy Cross Mts, Poland, is based on the widely accepted assumption that heterothecae increase in thickness by successive overgrowth of the conical tabulae. The calculations based on 50 corallites with 39 thin sections prove apical angles from 1 to 7, commonly 1.5 to 2.5 degrees; the calculated height of the distal cone varies from 4 to almost 200 mm. Preliminary calculations for the Carboniferous genera Heterophyllia and Hexaphyllia prove similar values of apical angles; on the other hand in Longlinophyllia Lin & Wu this angle attains 40 degrees.

Wrzołek Tomasz, 1993: Variability in the Devonian tetracoral Phillipsastrea lacunosa (Gürich). Courier Forschungs-Institut Senckenberg 164, 293–300, Frankfurt-am-Main.
    Described and illustrated are over 40 colonies of Phillipsastrea lacunosa from the Upper Frasnian smithi Zone of the Holy Cross Mountains, Poland. The corals are phaceloid to pseudocerioid, with thick internal septothecae surrounding tabularia; the latter are without septa. 3 subspecies are distinguished within the material studied: Ph. lacunosa lacunosa (Gürich), predominantly phaceloid, with gently concave tabulae; Ph. lacunosa smithi (Różkowska), typically pseudocerioid, with larger corallites; Ph. lacunosa mariae subsp. n., morphologically intermediate between the former subspecies, with tabulae commonly flat. Distinction of subspecies rather than species is justified by presence of forms intermediate between these three morphotypes. [original abstract]

Wrzołek Tomasz & Wach Piotr, 1993: Tetracoral genus Spinophyllum in the Devonian of the Holy Cross Mts, Poland. Geologia 12/13 (Prace Naukowe Uniwersytetu Śląskiego w Katowicach 1331), 47–63, Katowice.
    Described and illustrated are the Holy Cross Devonian tetracorals with radial septal arrangement and carinate septa. They are assigned to the genus Spinophyllum Wedekind, 1922, synonymous with Truncicarinulum Yu et Kuang, 1982 and Charisphyllum Oliver et Sorauf, 1988.
Of the three described species two, S. longiseptatum (Lütte) and S. aiense aiense (Soshkina), occur in the Upper Givetian (equivalents of Temnophyllum occidentale Zone); the third species, S. aiense liujingense (Yu et Kuang) is from the Frasnian Zones Macgeea-Thamnophyllum up to Phillipsastrea smithi.

Coen-Aubert Marie & Wrzołek Tomasz, 1991: Redescription of the rugose coral Macgeea (Rozkowskaella) sandaliformis (Różkowska, 1980) from the Upper Frasnian of the Holy Cross Mountains (Poland). Bulletin de l'Institut royal des Sciences Naturelles de Belgique, Sciences de la Terre 61, 5–19, Bruxelles.
    The discovery of horseshoe dissepiments at the base of some coralla of Trigonella sandaliformis Różkowska, 1980, type species of Rozkowskaella Wrzołek, 1987 from the Upper Frasnian of Poland, leads to consider this taxon as a subgenus of Macgeea Webster, 1889. Moreover, Debnikiella Różkowska, 1980. whose type species is D. formosa Różkowska, 1980, also from the Upper Frasnian of Poland, can probably be placed in synonymy with Rozkowskaella. For comparison, a few topotypes of Pachyphyllum solitarium Hall & Whitfield, 1873, type species of the genus Macgeea are described. [original abstract]

Wrzołek Tomasz, 1988: Tetracoral zonation of the stromatoporoid-coral limestones, southwestern Holy Cross Mts, Poland. In: N. J. McMillan, A. F. Embry & D. J. Glass (eds): Devonian of the World, Canadian Society of the Petroleum Gelogists, Memoir 14, 3, 413–423, Calgary.
    Analysis of the distribution of 80 species recognized by the author in the stromatoporoid-coral limestones of the southwestern Holy Cross Mts, Poland, allows the recognition of 7 biozones and 2 biohorizons:
    1. Disphyllia laxa Oppel-Zone (associated with Stringocephalus burtini), recognized also in Moravia (Galle, 1985),
    2. Temnophyllum occidentale Range-Zone, with index species known also from the Upper Givetian of Australia,
    2A. Acanthophyllum sp. n. zone, informal, with typical Givetian genera Acanthophyllum, Grypophyllum, Stringophyllum,
    3. Disphyllum Acme-Zone, with the topmost Givetian (?) Hexagonaria davidsoni biohorizon in its lowert part; the latter species occurs significantly higher in western Europe (Coen-Aubert, 1982),
    4. Macgeea-Thamnophyllum Acme-Zone, with Hexagonaria aff. hexagona biohorizon at the bottom,
    5. Phillipsastrea smithi Oppel-Zone, and
    6. Frechastraea pentagona Oppel-Zone, the two latter within the detrital and marly limestones, overlying the typical stromatoporoid-coral complex; taxonomically most differentiated and with species recorded also in the high Frasnian of Devonshire (Scrutton, 1968), Belgium (Sorauf, 1967, Coen-Aubert, 1977, Tsien, 1977), western Germany (Birenheide, 1978) and Moravia (Galle, 1985).
    The Zones are mostly separated by intervals either impoverished in or devoid of tetracorals. [original abstract]

    The skeleton of the heterocoral Oligophylloides pachythecus Różkowska, 1969 from the Famennian of the Holy Cross Mountains is built of calcitic scales arranged parallel to the margins of heterotheca, surfaces of tabulae and septal flanks. Some Carboniferous Hexaphyllia and Heterophyllia investigated for comparison show a similar microstructure. Fibrous microstructure was not observed in any of the three genera, though it may be present in the median parts of the septa that are difficult to study. [original abstract]

Wrzołek Tomasz, 1981: Rugose coral Cyathophyllum diffusum sp. n. from the Frasnian deposits of the Holy Cross Mts. Acta Geologica Polonica 31(3–4), 169–175, Warszawa.
    The rugose coral Cyathophyllum diffusum sp. n. from the Upper Frasnian marly limestones of the Holy Cross Mts, Central Poland, is described. The new species has got dispersed trabeculae in the peripheral parts of septa. Distally convex blisters, i.e. the intraseptal dissepiments, connect the dispersed trabeculae of a septum. Another type of intraseptal dissepiments is demonstrated in the species Iowaphyllum mutabile Tsien, 1977, from the Frasnian limestones of the same region; in this species intraseptal dissepiments disrupt continuity of trabeculae and are the particular type of lonsdaleoid dissepiments.

Wrzołek Tomasz, 1980: Coral growth in Oligophylloides pachythecus Różkowska, 1969. Acta Palaeontologica Polonica 25(3–4), 513–517, Warszawa.
    Coral growth in Heterocorallia is described and illustrated for the first time. It has been studied in Oligophylloides pachythecus Różkowska, 1969 from the Upper Famennian of the Świętokrzyskie (Holy Cross) Mountains, Poland. One single offset at a time was formed laterally with respect to the parent polyp. It did not inherit any septa from the parent corallite forming its own, independent set of septa. The young polyp was for a long time connected with the parent by soft tissue being separated from its skeleton by a tabulotheca. The theca and possibly all the other skeletal elements of the species studied grew centrifugally. Evidence is presented that O. pachythecus had a distal part of its corallite in the shape of a slender distal cone with a set of septa protruding on top of the cone. [original abstract]
