“…In addition to the genes, we also assembled a database that included all the fossils described for each group with its respective ages and locations. The fossil record of the Acanthuridae includes 25 species belonging to 19 extinct genera, most described from the Eocene of Monte Bolca (Bannikov & Tyler, ; Tyler, , ; Tyler & Bannikov, ; Tyler & Micklich, ). Similarly, the Siganidae has 10 described fossil species in eight extinct genera (Bannikov & Tyler, ; Bannikov et al, ; Tyler & Bannikov, ).…”

“…Our constraints for the surgeonfish phylogeny were firstly based on subfamily groupings, with two extinct subfamilies (Padovathurinae and Gazolachthyinae, Tyler, 2005aTyler, , 2005b, and the Nasinae and Acanthurinae including extant and extinct taxa (Tyler & Micklich, 2011;Winterbottom, 1993). The later was also split between higher and lower Acanthurinae according to the groupings in Tyler and Micklich (2011). The fossils of unknown status within the Acanthurinae (Tyler & Micklich, 2011) were treated as a separate clade in the subfamily.…”

“…The early history of some extant herbivorous reef fish groups is well documented in the fossil record (Bannikov, Tyler, & Sorbini, ; Tyler & Micklich, ). The richness of surgeonfish (Acanthuridae) and rabbitfish (Siganidae) fossils from the Eocene suggests that they have been important components of reef‐associated faunas for at least 50 million years (Myr) (Bellwood, ).…”

Aim To describe the global biogeography of key herbivorous coral reef fish groups since their presumed origins, using data from both fossil and extant species. Location Global Cenozoic reefs. Taxon Acanthuridae (surgeonfishes), Siganidae (rabbitfishes) and Scarini (parrotfishes). Methods We applied the fossilized birth–death model to build chronograms including a comprehensive sampling of extant species and all the fossil occurrences described for each group. With the resulting chronograms, we built biogeographical models considering the geological changes in reef habitat availability since the ancient Tethys Sea. Finally, we used biogeographical stochastic mappings to trace the routes of colonization of the Atlantic Ocean by lineages in our focal taxa. Results We found that the Palaeocene–Eocene was a period of significant lineage origination for surgeonfishes and rabbitfishes in the central Tethys Sea with the appearance of ancient genera. Most of these genera were probably extinct by the Eocene–Oligocene boundary as they do not correspond with modern taxa. Parrotfishes, however, originated in the early Oligocene, an epoch that corresponds with the geographical transition of the marine biodiversity hotspot. In all groups, extant genera had similar origin times and all expanded in the Miocene, mainly in the Indo‐Pacific. In the Atlantic, only one parrotfish lineage with Tethyan ancestry appears to have survived. It subsequently gave rise to extant endemic genera (Sparisoma and Cryptotomus). The other extant lineages in the Atlantic all have Indo‐Pacific origins and colonized more recently using different dispersal pathways. Main conclusions The Indo‐Pacific herbivorous fish fauna is the result of ongoing lineage expansion that started in the central Tethys. The Atlantic is a composite fauna with just one endemic lineage and at least four colonization events from the Indo‐Pacific.

“…Today, in both surgeonfishes (Acanthuridae) and rabbitfishes (Siganidae), the number of fossil genera greatly exceeds Recent taxonomic diversity [23,24]. This is most marked in the surgeonfishes where we have 14 Eocene genera compared to just five genera today [24]. In rabbitfishes, we have three Eocene genera versus one today [23].…”

Fifty million years of herbivory on coral reefs: fossils, fish and functional innovations

The evolution of ecological processes on coral reefs was examined based on Eocene fossil fishes from Monte Bolca, Italy and extant species from the Great Barrier Reef, Australia. Using ecologically relevant morphological metrics, we investigated the evolution of herbivory in surgeonfishes (Acanthuridae) and rabbitfishes (Siganidae). Eocene and Recent surgeonfishes showed remarkable similarities, with grazers, browsers and even specialized, long-snouted forms having Eocene analogues. These long-snouted Eocene species were probably pair-forming, crevice-feeding forms like their Recent counterparts. Although Eocene surgeonfishes likely played a critical role as herbivores during the origins of modern coral reefs, they lacked the novel morphologies seen in modern Acanthurus and Siganus (including eyes positioned high above their low-set mouths). Today, these forms dominate coral reefs in both abundance and species richness and are associated with feeding on shallow, exposed algal turfs. The radiation of these new forms, and their expansion into new habitats in the Oligocene–Miocene, reflects the second phase in the development of fish herbivory on coral reefs that is closely associated with the exploitation of highly productive short algal turfs.

First record of Acanthuridae (surgeonfish) from the Miocene deposits of the Medvednica Mt.

Middle Miocene deposits at the Dubravica locality in SW Medvednica Mt. (N Croatia) contain various marine fossils, including one tooth of the surgeonfish (Acanthuridae). This is the first such record in Croatia and the second in the wider region, besides the Vienna Basin. The appearance of surgeonfishes in the Paratethys coincides with the Miocene thermal maximum. Their distribution was probably controlled by available reef habitat and their palaeobiogeography and migration routes are yet to be studied.
