“…Focusing on the Cenozoic, several studies have shown the relative abundance of reef builders and other major carbonate producers through the Paleogene and Neogene (e.g., Kiessling and Baron-Szabo, 2004;Baceta et al, 2005;Pomar and Hallock, 2008;Wilson, 2008, Scheibner andSpeijer, 2008;Perrin and Kiessling, 2010;Zamagni et al, 2012;Höntzsch et al, 2013). These studies have revealed several steps in the rise of coralgal associations as chief reef builders: (1) Coralgal reef communities survived the crisis at the Cretaceous-Paleogene (K-Pg) transition, and were able to construct substantial buildups by the middle Danian, only 1.5-2 Ma after the K-Pg boundary.…”

“…Paradoxically, while other groups declined in diversity and prominence, scleractinian corals maintained the high diversities attained in the Eocene, while greatly expanding in their role as reef builders, particularly by the Late Oligocene (Budd, 2000;Perrin, 2002). After a transient platform crisis during the earliest Oligocene, coral reefs spread throughout the Tethys and proliferated with new lineages of larger benthic foraminifers (Höntzsch et al, 2013). During the Late Oligocene, coral reefs spread throughout the Tethys regions (Frost, 1977;Frost et al, 1983) and were also diverse in the Caribbean and the Indo-Pacific regions (Budd, 2000;Wilson, 2008).…”

Characterizing these attributes has been approached by 1) building reference models for specific Phanerozoic intervals, 2) recognizing the climatic impact in modulating carbonate production, and 3) analyzing the influence of changing bio-geochemical conditions. The reference-model approach is mostly based on biological evolution, the climaticimpact approach emphasizes temperature, and the bio-geochemical approach considers the changes in Mg/Ca ratios and Ca ++ concentrations in the oceans. To date, however, an analysis integrating all of these factors is still missing. The analysis presented here includes all these factors but also CO 2 , which is fundamental for both photosynthesis and CaCO 3 precipitation.Here we analyze the waxing and waning of Cenozoic reef limestones from the central Tethys region through several steps: 1) on the basis of rock volume, rock textures, associated sediments and light-dependent skeletal components, as records of light penetration and wave energy (depth); 2) on global environmental conditions (δ 13 C, δ 18 O, pCO 2 , temperature); and 3) on the basis of functionality, nutritional requirements and available resources.Through the Cenozoic, water motion, whether induced by surface or internal waves or by currents, increased as the thermal gradients strengthened, both with depth and with latitude. Active water motion is essential for plankton catchers such as corals, but less so for many larger benthic foraminifers (LBF). Pycnoclines in the meso-oligophotic zone would then favor the benthic plankton catchers such as corals, but would be detrimental for many LBF. Warm temperatures favored LBF. The Eocene LBF families predominated during lowering of atmospheric pCO 2 by using respiratory CO 2 to enhance the symbiont production of photosynthates under oligotrophic conditions and limited turbulence, whereas the Miocene families had to adapt to a progressive increase in turbulence. The eurythermal coralline red algae, however, became preponderant producers in the mesophotic zone during times when the δ 13 C was relatively high. This explains two apparent paradoxes: 1) corals thrive best when the Earth's high latitudes cool, and 2) the dominance of corals and LBF is inversely correlated, despite they both require tropical conditions and have similar trophic strategies (mixotrophy).

“…The Transylvanian reefs exemplify the coral buildups of the northern Tethys characterized for the Stage V (Priabonian). This stage is defined by the demise of many symbiont‐bearing larger foraminifers, development of the first larger coral buildups in the northern Tethys and recovery of coral assemblages in the southern Tethys (Höntsch et al, ). The demise of many large benthic foraminifers and their replacement by coral communities in the Late Eocene was also recognized by Nebelsick et al (, ).…”

Coral reefs near the Eocene–Oligocene boundary in the northern Transylvanian Basin, Romania: Composition and paleoenvironmental interpretation

2017

Eocene–Oligocene reefs have been reported in Europe largely from the circum‐Mediterranean region. In this paper, small coral reefs from the northwestern Transylvanian Basin (Romania) are described for the first time. They developed near the Eocene–Oligocene boundary, most probably during the Priabonian, and belong to northernmost outposts of the reef belt developed during this time in Europe. The studied sedimentary successions in Letca and Băbeni–Cuciulat (Sălaj County), up to 55 m thick, belong to the Cozla Formation. The reefs occur within a shallow‐water succession composed mostly of bedded limestones, dominated by bioclastic (coralline) packstones. Low‐relief (constratal) reefs, locally up to 10–15 m in thickness, are spaced cluster (matrix‐supported) reefs. Scleractinian corals are common but poorly diversified (10 species and 8 genera). Branching ramose colonies, branching low‐integrated phaceloid, and sheet‐like (foliaceous) corals dominate. Neither lateral zonation nor vertical succession of reefs was recognized. Corals co‐occur with encrusting and geniculate red algae, but they are of subordinate significance for a nonrigid reef framework. Branching corals baffled or trapped suspended carbonate mud that contributed to the reef growth and ongoing development of topographic relief. Associated fossils are of low to moderate diversity. A relatively low‐energy environment, moderate to high sedimentation rate, and increased turbidity are inferred from carbonate muddy and fine‐grained matrix, dominance of sediment‐resistant corals, their morphology, common occurrence in growth position, as well as low to moderate degree of bioerosion and encrustation. Transylvanian reefs in terms of poor coral diversity, matrix‐supported texture, and turbid‐water sedimentary setting show similarities with many coeval reefs from the circum‐Tethyan area.
