The mid−septal zone corresponds to the position of calcification centers in skeletons of extant corals, whereas the flank areas to the zone have longer aragonite fibers. Calcification centers, which originated during the first phase of septal formation, are composed of minute aragonite crystals and are rich in organic components, whereas zones with fibers, originated during the next, successive phases of septal growth, contain a smaller amount of organic components. As stated by +Sorauf and Cuif (2001: 161) +: “primary septal area with greater content of organic matrix underwent diagenesis separately, and possibly earlier than the secondary skeleton, with diagenesis of primary septum preserving more inclusions”.

Initial portions of adult coralla, exposed by light etching ( +Fig. 4C +) and initial or early juvenile specimens attached to adult coralla ( +Fig. 4B + +1 + +, B + +2 + +) are twelve−septate and have a similar diameter. Juvenile coralla attached to the same small−sized substratum may adhere to themselves ( +Fig. 2A + +1 + +, A + +2 + +). Such double calices possess independent epithecate walls in their contact zone (arrow in +Fig. 2A + +1 + +). Seemingly similar coralla with two calices may develop from a single but regenerated calice ( +Fig. 2D + +1 + +, D + +2 + +). In contrast to the “adhering” specimens, two “regenerated” calices share some skeletal elements, e.g., septa of higher cycles (arrow in +Fig. 2D + +4 + +) and do not develop an epithecate wall in the contact zone between calices. Calices disintegrated into several, not clearly defined zones ( +Fig. 2C +), showing asymmetrical constriction ( +Fig. 5A, B +), or constricted repeatedly two or more times ( +Fig. 2G +) have also been observed. + + + +Fig.2. + +Haimeicyclus haimei +(ChapuisandDewalque,1853) + +. +A +.IPUM−Sic.92a,bwithtwocalicesindistal(A +1 +)andproximal−lateral(A +2 +)views.Calicesareseparatedbyepithecalwalls(arrowinA +1 +)andresultedfromgrowthoftwojuvenilesattachedtocommonsubstrate. +B +.DistalviewofIPUM−Sic.82.TwelveS1–2arrowed. +C +.

Septa S1–3 reach calicular center; S4 extend to ca. 3/4 of the calicular radius; S5 to the half of the calicular radius, and S6 are developed only at calice periphery. All septa consist of spines that lower in fossa are covered with sclerenchyme and form a compact septum. In lower cycle septa (S1–3), individual spines are recognizable only on their distal edge whereas septa of higher cycles, especially of ultimate or penultimate cycles, composed of spines individualized in distal and proximalpartsofcalice( +Fig.5B,C +).Surfaceofspinescoveredwith dense granulations ca. 40–50 µm in diameter. Lower in calice, septal faces covered with thicker layers of sclerenchyme and become smoother, except for places with septal spines still projecting through sclerenchymal deposits. Skeleton completely recrystallized, calcitic (confirmed by X−ray diffraction). Epithecate wall spread on entire proximal side and in largerspecimensslightlymorecylindrical,bendingupwards. + + + + +Remarks +.—InmostScleractiniathelengthoftheseptacorrelates with the order of their appearance. Septa of the first cycle, inserted at the beginning of the coral skeletogenesis are usually much longer and thicker in comparison to the septa of higher cycles inserted later in ontogeny (however, one of the exceptions is + +Schizocyathus fissilis +Pourtalès, 1874 + +with S2<S +3 in +adult coralla. S +2 in + +S. fissilis + +degenerate during corallum growth, most likely because of functional involvement in corallum longitudinal division; see +Stolarski 2000 +). On the other hand, in + +Zardinophyllum zardinii +Montanaro−Gallitelli, 1975 + +(representative of pachythecaliines—supposed rugosan descendants), the first 6 initial septa are not inserted simultaneously and this is reflected in their unequal length and thickness ( +Stolarski 1996 +, 1999). Because the first twelve septa of initial and early juvenile coralla of + +H. haimei + +( +Fig. 4B + +1 + +, B + +2 + +, C) have similar length and thickness, one may infer that they were inserted simultaneously and thus the early ontogeny follows a cyclic pattern recognized in typical scleractinians. + + +Juvenile coralla (but also serpulid tubes) are occasionally found attached to both sides of adult coralla (e.g., +Fig. 4D + +1 + +, D + +2 + +). Such coralla do not show any defensive reaction against incrustation (e.g., constrictions of the corallum diameter as in +Fig. 2C +) and it is clear that juveniles could not grow on the proximal side of adult coralla without inverting position of the latter. Thus, most likely, adult coralla were incrusted while dead, and incrustations on both sides were possible because of occasional rolling on such skeletons. On the other hand, the situation when juveniles are attached only to the substrate that also serves adults ( + +Fig. 4B +4 + +) suggests that only the substrate was rolled and not the adult corallum. Judging by the transitional spectrum of morphologies of incrusting initials and juveniles, and by comparisons with initial and juvenile portions of adult coralla, all juveniles incrusting adult coralla belong to the same species. Attachment of juveniles to the adult coralla of the same species were observed in extant (Gerodette 1981; Fadlallah and Pearse 1982) and fossil corals ( +Stolarski 1995 +). In modern seas, corals that produce such settling larvae are brooders releasing large, benthic crawling planulae. Initial coralla that develop after metamorphosis of such large, benthic planulae often exceed +2 mm +in diameter (see +Squires 1962 +; Gerodette 1981; Fadlallah and Pearse 1982). The occurrence of numerous juveniles attached to adults in + +H. haimei + +may suggest similar benthic behavior, however, much smaller size (ca. +1 mm +in diameter) favors a scenario in which local hydrological conditions forces part of the coral “spat” to settle on available hard substrates, i.e., the adult coralla. + + +The skeleton of + +H. haimei + +is competely recrystallized (calcitic), however, dense and homogenous granulation on septal spines conform to a “coarse” texture observed on septa of the below described + +Stylophyllopsis +cf. +rugosa + +and thus implies similar microstructure (see Discussion). + + + + +Fig. 4. + +Haimeicyclus haimei +( +Chapuis and Dewalque, 1853 +) + +. +A +.

S3 extend to ca. 3/4 of the calicular radius, S4 may reach half of the calicular radius (then often occur short S5) but can be much shorter (then S5 are not developed). Septal spines may dissociate from the lower cycle septa (S1–3) in axial region, but in coralla with damaged uppermost parts, septal spines are distinguishable in sections by bulbous axial septal portions. Septal faces are smooth or, occasionally, covered with minute granulations. In transverse section, septa are spindle−shaped with a well−developed costal part that is covered with pellicular epitheca (e.g., +Fig. 10A + +1 + +, A + +2 + +).

As in + +Stylophyllopsis +sp. + +cf. + +S. rugosa + +, darker and lighter coloration of some distinct structures can be distinguished. Often, in transverse sections of proximal portions of corallum, a distinct mid−septal zone is visible ( +Figs. 9B, D +, +10A + +2 + +). This narrow and often dark zone occurs as a semi−continuous “line” in costal parts of septa but in axial septal portions it dissociates into modules, often restricted to the bulbous septal portions ( +Fig. 10A + +2 + +). Commonly, several smaller units may be seen within a mid−septal zone; these are much smaller bodies of about 80µm in diameter of dark ( +Fig. 9D +) but also light ( +Fig. 10A + +2 + +) coloration. In more distal portions of the same coralla (e.g., +Fig. 9C, E +), the mid−septal zone may still occur in costal portions of septa, but oval structures with diagenetic pattern similar to that in septal spines of + +Stylophyllopsis +sp. + +cf. + +S. rugosa + +(see +Fig. 7E +) often occur there. + + + + +Remarks +.—Sections of nine Sicilian specimens (IPUM−Sic.1, 2, 4, 6–8, 10–12) show a consistent pattern of skeletal diagenetic alteration. Anarrow, mid−septa zone, often composed of row of about 80 µm bodies, can be seen in transverse sections of septa, particularly from the proximal corallum parts. Small−sized bodies represent, most likely, vestiges of calcification centers. In this respect, + +Stylophyllopsis +sp. A + +. resembles “minitrabecular” corals (= + +Caryophylliina +sensu +Roniewicz 1989 + +), in which the mid−septal zone consists of numerous, small−sized calcification centers aligned in a row or zig−zag line ( +Fig. 10B + +1 + +, B + +2 + +; see also +Roniewicz 1984 +; RoniewiczandMorycowa1993).Alsospindle−likeshapesoftransversely sectioned septa strengthen similarity with “minitrabecular” corals (compare +Fig. 10A + +2 + +and +10B + +1 + +, B + +2 + +). However, spines that dissociate from adaxial regions of some septa or are distinguished in sections as series of bulbous septal swellings with individual mid−septal zones ( +Fig. 10A + +2 + +), suggest transitional minitrabecular−stylophylline skeletal architecture of that species.
