Sulcichnus maeandriformis ichnosp. nov.
Figs. 3 View Fig , 4I–L View Fig .
Etymology: After the Latin words maeander, meander and formis, form.
Type material: Holotype, MMPE /Ic001.001.001 (Velerín, Estepona) ( Fig. 3C View Fig ) . Paratypes, MMPE /Ic001.003.001 (Bizcornil, Estepona) ( Fig. 3A View Fig ) , MMPE/Ic001.002.001 (Velerín, Estepona) ( Fig. 3B View Fig ), MMPE/ Ic001.004.001 (Velerín, Estepona) ( Fig. 3D View Fig ), MMPE/Ic001.005.001 (Velerín, Estepona) ( Fig. 3E View Fig ), JMC−UB/I−0087 (Vila−robau, Alt Empordà) ( Fig. 3F View Fig ).
Type locality: Velerín , Estepona Basin, E Andalusia, Spain .
Type horizon: Upper Zanclean (Pliocene) silts, Estepona Basin, Málaga ( SE Spain) ( Aguirre et al. 2005) .
Material.—Number of specimens: 9 from Rio Torsero, Liguria; 2 from Alpes−Maritimes; 5 from Vila−robau, Alt Empordà; 4 from Baix Llobregat; 1 from Níjar−Almería; 1 from Bizcornil, Estepona; 1 from Padrón, Estepona; 4 from Parque Antena, Estepona; up to 30 from Velerín, Estepona ( Table 2).
Diagnosis.—Deep groove of relatively constant width that takes various sinuous forms.
Description.—Deep grooves (2 mm maximum) of relatively constant width in every specimen (between 1–2 mm) that describe various gentle undulations to tighter loops, although in the latter the opposite parts of the figure never parallel. The grooves normally begin and end at the edge of the calyx and sometimes show one or two short branches. The trace is often very symmetrical from one side of the corallite to the other in flabellate forms. In them, the central, lower part of the figure surrounds the corallite and the two extremes run more or less vertically to the calyx ( Fig. 2 View Fig ).
Remarks.—This trace appears in specimens of all four coral morphologies considered: flabellate, trochoid, conical to turbinate, and turbinate to ceratoid ( Table 3). It also appears on specimes of Trochocyathus coming from the Miocene of Turin ( Italy) (MHNUT). Some Recent specimens sawn in the literature are also according with this pattern ( Zibrowius et al. 1975).
Stratigraphic and geographic range.—Tortonian (Late Miocene) to Recent; worldwide.
