“…Because of their hypermineralized nature, teeth are also more easily fossilized than skeletal remains, and even make the bulk of the fossil record of certain groups, such as chondrichthyans, of which complete skeletons remain scarce (Cappetta, , ). More recently, they have drawn the attention of physicists (Enax et al ., ), geochemists (Fisher et al ., ), and archaeologists (Cione & Bonomo, ; Drew, Philipp & Westneat, ), demonstrating that teeth and their various properties are indeed at the interface between numerous disciplines.…”

“…In contrast, others have maintained that they comprised elements of an endemic freshwater ecosystem because the strontium isotope ratio ( 87 Sr/ 86 Sr) of apatite tooth enamel (0.70824–0.71216) suggests substantial contact with continental‐influenced water bodies (Masson & Rust ; Stamberg & Zajíc ; Fischer et al . , ; Montañez & Cecil ).…”

“…However, consensus regarding ecology is currently lacking, with some researchers arguing on palaeogeographical, sedimentological and geochemical grounds that fish taxa, especially xenacanthid sharks (Masson & Rust ) and tetrapods, may have been obligate freshwater organisms (Johnson , ; Stamberg & Zajíc ; Fischer et al . , ; Montañez & Cecil ).

42The cosmopolitan biogeography of many fish genera strongly indicates marine-based 43 dispersal, while strontium isotopic data suggest these same fish were exposed, at times, to ). An intriguing characteristic of this episode was the apparent widespread adoption of 68 a euryhaline habit amongst organisms as diverse as microconchids, ostracodes, xiphosurans 69 and fish (Anderson and Shuster 2003; Carpenter et al. 2011; Bennett et al. 2012; Gierlowski-70 Kordesch and Cassle 2015). Euryhaline animals are relatively rare in modern ecosystems 71 (Edwards and Marshall 2013; McCormick et al. 2013), and their dominance in Carboniferous 72 times suggests marine communities converged on similar osmoregulatory strategies in order 73 to utilise empty non-marine coastal ecospace for feeding and breeding (Williams et al. 2006; 74 Carpenter et al. 2014), prior to the widespread colonisation of freshwater tracts further inland. 75The mid-Carboniferous diversification event coincided with a sharp growth of 76Gondwanan ice sheets and the onset of significant Milankovitch-driven glacio-eustatic 86Much recent attention has been given to the apparent dominance of a euryhaline mode 87 of life amongst mid-Carboniferous fish communities (Schultze 2009; Carpenter et al. 2011 Carpenter et al. , 88 2014Carpenter et al. , 2015. However, consensus regarding ecology is currently lacking, with some 89 researchers arguing on palaeogeographic, sedimentological and geochemical grounds that fish 90 taxa, especially xenacanthid sharks (Masson and Rust 1984), may have been obligate 91 freshwater organisms (Śtamberg and Zajíc 2008;Fischer et al. 2011 Fischer et al. , 2013 Montañez and 92 Cecil 2013). In this paper, we describe a new fish fauna from the Carboniferous 93 (Pennsylvanian) of New Brunswick, Canada (Fig. 1A), and demonstrate -based on 94 independent indicators of palaeo-salinity -that fish taxa existed across a brackish to marine 95 gradient, and that communities must therefore have been euryhaline. We discuss how these 96 new findings improve understanding of Carboniferous fish ecology and the mid- 97Carboniferous diversification of non-marine ecosystems in particular. The fish fossils reported here were obtained from opencast mine sites (now reclaimed) within 102 the Minto Coalfield, Queens County, New Brunswick, Canada (Fig. 1A-C 98 +REVISE FOR TETRAPOD STORY 123Extensive borehole arrays indicate that this basal unconformity is marked by a major silcrete 124 paleosol, up to 9 m thick in places (Sullivan 1981; St Peter 2000), which mantles the 125 basement complex and indicates seasonally-dry climate weathering over the preceding (Fig. 3A), implying that the basin deepened towards the 137 southwest, and sediment progressively onlapped towards the northeast; and (2) NE-SW- Coal, fine towards the southwest (Fig. 3B) and suggest sediment transport in that direction. 140We note, however, that this inferred palaeoflow direction opposes regional patterns of Geological Surveys Branch, Fredericton (Fig. 4A). 154The low...

“…However, Δ carb‐phos offsets vary among species but are also dependent on various methodologies used to measure the δ 18 O phos and δ 18 O carb values, different pretreatment procedures, different precipitation methods for bioapatite phosphate or carbonate extraction methods, and different instruments employed . The lack of suitable international bioapatite materials makes it difficult to identify the reasons for the deviations (see Fischer et al for discussion). All these factors together complicate the comparison of the results of different studies.…”

Rationale The use of multi‐isotopic analysis (δ2H, δ13C, δ15N, δ18O, and δ34S values) of modern human body tissues for provenancing of unknown individuals in forensics is increasing. Tooth dentine develops during childhood and adolescence, therefore providing geographical information from that period of life. Tooth apatite δ18O values are commonly used for the reconstruction of drinking water values, and H–C–N–S isotope ratios in collagen supply additional information about the composition of diet. We tested if dentine collagen δ2H values provide similar information to apatite δ18O values with a proof‐of‐concept study. Methods Tooth samples were taken from modern‐day individuals born in different regions of the world. Apatite and collagen were prepared from dentine. Stable isotope analyses were performed on apatite phosphate oxygen (δ18Ophos); oxygen and carbon of the structural carbonate (δ18Ocarb, δ13Ccarb); and hydrogen, carbon, nitrogen, and sulfur of the collagen (δ2Hcoll, δ13Ccoll, δ15N, δ34S). Results δ18Ophos, δ18Ocarb, and δ2Hcoll values are highly correlated in modern human dentine. There are significant relationships of δ18O values in the apatite fraction and δ2H values in the collagen fraction with local δ18O and δ2H precipitation values, respectively. Pearson correlation coefficients indicate no direct relationship between δ15N values and the isotope ratios of any other element. Weak relationships exist between collagen δ34S values and δ18Ocarb or δ18Ophos values. Conclusions The highly significant correlation of δ18Ophos, δ18Ocarb, and δ2Hcoll values in the modern human dentine implies that measurement of δ2H values in collagen or δ18O values in bioapatite will provide reliable information about the climate at the person's whereabouts.
