“…Microtomography provides high-resolution three-dimensional reconstructions of mineralized tissues [22,26], allowing the virtual segmentation and investigation of both pharyngeal bones and teeth, but not the KCP. Thus, it was possible to scrutinize the number and arrangement of pharyngeal teeth, as well as individual shape of tooth crowns.…”

“…Right and left sets of pharyngeal teeth do not interlock but together occlude against a keratinized chewing pad (KCP) that covers the pharyngeal plate of the basioccipital [21]. Across the order, there is great diversity in the arrangement, number and shape of pharyngeal teeth [22]. Some species have one row encompassing numerous teeth while others have three rows with fewer teeth on each row.…”

Stability versus diversity of the dentition during evolutionary radiation in cyprinine fish

Evolutionary radiations, especially adaptive radiations, have been widely studied but mainly for recent events such as in cichlid fish or Anolis lizards. Here, we investigate the radiation of the subfamily Cyprininae, which includes more than 1300 species and is estimated to have originated from Southeast Asia around 55 Ma. In order to decipher a potential adaptive radiation, within a solid phylogenetic framework, we investigated the trophic apparatus, and especially the pharyngeal dentition, as teeth have proved to be important markers of ecological specialization. We compared two tribes within Cyprininae, Poropuntiini and Labeonini, displaying divergent dental patterns, as well as other characters related to their trophic apparatus. Our results suggest that the anatomy of the trophic apparatus and diet are clearly correlated and this explains the difference in dental patterns observed between these two tribes. Our results illustrate the diversity of mechanisms that account for species diversity in this very diverse clade: diversification of dental characters from an ancestral pattern on the one hand, conservation of a basal synapomorphy leading to ecological specialization on the other hand. By integrating morphological, ecological and phylogenetic analyses, it becomes possible to investigate ancient radiation events that have shaped the present diversity of species.

“…For example, the short and broad pharyngeal bones, while bearing molar teeth, are good at dealing with invertebrates (e.g., insects and mollusks); the intermediate pharyngeal bones and diverse morphotypes of teeth (conical, coarsely compressed and extremely compressed) are adapted to a large variety of foods including both algae and aquatic insects; and the long and narrow pharyngeal bones usually bearing extremely compressed teeth are suited for herbal diets (e.g., algae and plant debris) (Eastman, 1977;Sibbing, 1982Sibbing, , 1991aLiem & Sanderson, 1986;Zeng & Liu, 2009). While the contribution of pharyngeal bones to diversification of cichlids and their evolutionary process has been documented in detail (Liem & Sanderson, 1986;Hulsey, 2006), studies on evolutionary pattern and process of pharyngeal bones and teeth in cyprinids are scarce (Pasco-Viel et al, 2010). It has been suggested that cyprinid pharyngeal bones and teeth may bear important systematic value.…”

The subfamily Gobioninae is a subgroup in the specious fish family Cyprinidae, which bears high diversity in morphological and ecological dimensions and has its most components distributed in East Asia. In this study, the pharyngeal bones and teeth of 39 species belonging to 19 genera of the Gobioninae were examined, with the phylogenetic comparative method (PCM) and correlation methods employed to analyze the character evolution. Three characters on pharyngeal bones (shape of the pharyngeal bones, extension for attachment of the pharyngo-cleithralis internus posterior (PCIP) muscle, and teeth-bearing area) and six characters of pharyngeal teeth (shape of the five teeth in the main row, number of rows of the teeth) were identified and compared. When the character states were mapped on a molecular phylogenetic tree, it was found that, to adapt to different masticatory operations, different Gobioninae species have various morphological types of pharyngeal bones and teeth: some have intermediate pharyngeal bones bearing multiple rows of diverse teeth (conical, coarsely compressed, and compressed), others have broad pharyngeal bones bearing a single row of molar teeth, and still others have narrow pharyngeal bones bearing a single row of extremely compressed teeth. Tests on the phylogenetic signal and evolutionary associations revealed that evolution of the examined characters was all phylogenetically constrained and correlated. Owing to the homoplasy in evolution, it was suggested that the conventional method of using pharyngeal bones and teeth for phylogenetic reconstruction of cyprinid fishes should not be encouraged.

The Lesvos Petrified Forest (western Lesvos, Greece) has long been famous for its plant fossils. Recently, one proboscidean (from the Gavathas locality) and seven micromammalian species (from the Lapsarna locality) were described; these were the first animals to be found in the Early Miocene subtropical forest. For the first time, a fauna of gastropods and ectothermic vertebrates from the Lapsarna locality is now available. This fauna derives from lacustrine sediments under the pyroclastic material that contains the petrified plants. Based on fragmented mollusc remains, isolated fish pharyngeal teeth and utricular otoliths (lapilli), fragmented amphibian vertebrae and a tooth-bearing element, and reptile fragmented dentaries, teeth, osteoderms and vertebrae, the presence of eight freshwater and three terrestrial gastropod species, three freshwater cyprinid species, and two amphibian and five reptile taxa has been confirmed. Stratigraphical and radiometric data suggest an age older than 18.4 ± 0.5 Ma (latest Early Miocene), in good agreement with the faunal composition. This paper is the first report of the concurrent presence of three cyprinid fish species in a Greek Early Miocene locality, as well as the first documentation of an Early Miocene proteid amphibian in southeastern Europe. The present findings represent one of the best-documented Early Miocene gastropod and fish faunas in the Aegean/southern Balkans, thus adding to our knowledge of Early Miocene amphibians and reptiles from that region and providing valuable information on the local subtropical ecosystem.
