“…The presence of numerous alcid species from the Miocene and Pliocene that are not known from Pleistocene and younger deposits agrees with the trends in faunal turnover that have been well documented in marine microfaunas and macrofaunas (Versteegh , Kameo and Sato ). For example, walrus, squalodon, albatross, and pelagornithids (giant pseudotoothed birds) were present in the northern Atlantic Ocean during the Miocene and Pliocene but are absent there today (Ray , Ray and Bohaska , Ray et al ). Likewise, Pacific Ocean diversity of other seabirds and marine mammals is also noted to decline from the Miocene to today (Repenning and Tedford , Warheit , Boessenecker , Boessenecker and Smith ).…”

Puffins, auks and their allies in the wing-propelled diving seabird clade Pan-Alcidae (Charadriiformes) have been proposed to be key pelagic indicators of faunal shifts in Northern Hemisphere oceans. However, most previous phylogenetic analyses of the clade have focused only on the 23 extant alcid species. Here we undertake a combined phylogenetic analysis of all previously published molecular sequence data (∼ 12 kb) and morphological data (n  353 characters) with dense species level sampling that also includes 28 extinct taxa. We present a new estimate of the patterns of diversification in the clade based on divergence time estimates that include a previously vetted set of twelve fossil calibrations. The resultant time trees are also used in the evaluation of previously hypothesized paleoclimatic drivers of pan-alcid evolution. Our divergence dating results estimate the split of Alcidae from its sister taxon Stercorariidae during the late Eocene (∼ 35 Ma), an evolutionary hypothesis for clade origination that agrees with the fossil record and that does not require the inference of extensive ghost lineages. The extant dovekie Alle alle is identified as the sole extant member of a clade including four extinct Miocene species. Furthermore, whereas an Uria  Alle clade has been previously recovered from molecular analyses, the extinct diversity of closely related Miocepphus species yields morphological support for this clade. Our results suggest that extant alcid diversity is a function of Miocene diversification and differential extinction at the Pliocene-Pleistocene boundary. The relative timing of the Middle Miocene climatic optimum and the Pliocene-Pleistocene climatic transition and major diversification and extinction events in Pan-Alcidae, respectively, are consistent with a potential link between major paleoclimatic events and pan-alcid cladogenesis.

“…In their review of amphibians and turtles from the Miocene Calvert Formation, Weems and George (2013) assigned a single posterior peripheral found in float to an indeterminate species of Trachemys. Zug (2001) also assigned a few isolated specimens from the Miocene-Pliocene Lee Creek Mine to "Chrysemys complex" and suggested that both Pseudemys and Trachemys were probably represented. Trachemys has been recognized from multiple Hemphillian faunas in North America including occurrences in Florida, Nebraska, and Tennessee (Hulbert (2001), Holman and Parmley (2005) and Parmalee et al (2002)).…”

The Lapara Creek Fauna: Early Clarendonian of south Texas, USA

The Lapara Creek Fauna includes a large collection of fossil vertebrates obtained by the StateWide Paleontologic-Mineralogic Survey in Texas (1939-1941) under the direction of the Bureau of Economic Geology and the Texas Memorial Museum. Of the 50 species of fossil vertebrates, five species are fish, seven are reptiles, two are birds and 36 are mammals. The 36 species of mammals represent 31 genera of which four are rodents, five are carnivores, two are proboscideans, 10 are artiodactyls and 10 are perissodactyls. These taxa are known from four separate local faunas distributed within the lower to middle parts of the Goliad Formation and are Clarendonian in age. The Ten Mile Waterhole Creek and Bridge Ranch local faunas compare well with Cl1 faunas in North America, while the Farish Ranch and Buckner Ranch local faunas compare well with early Cl2 faunas. The fauna includes the first occurrence, or at least very early occurrences, of cf. Trachemys sp., Apalone sp., Alligator cf. mississippiensis and cf. Eucyon sp. Identification of Ceratogaulus cf. rhinoceros extends the known geographic range of this taxon and represents the oldest occurrence of a mylagaulid from the Texas coastal plain. Blancotherium buckneri is a new generic name assigned to a longirostrine gomphothere that is represented by numerous specimens from the Buckner Ranch Local Fauna. The diverse horse fauna includes 12 species representing nine genera, all but one of which are hypsodont. The composition of the fauna is consistent with the widespread Clarendonian Chronofauna and with a mixed woodland-grassland environment on a broad floodplain associated with low-gradient rivers.

“…Given extinction has resulted in the loss of many breeding colonies of petrels since human colonisation, it is likely that more than one taxon each of small and medium petrels formerly bred in the Gambier Group, and certainly several would have and still do forage in the group. As noted by numerous authors, identification of petrels to genera based on skeletal elements is straightforward, but specific separation of congeneric similar-sized species, is often not possible on morphology alone (Wragg, 1995;Olson and Rasmussen, 2001;Tennyson et al, 2015). For example, Murphy and Pennoyer (1952: 1) noted that many of these species are so similar skeletally as to preclude their separation, stating "We have compared, for example, skulls of the species neglecta, arminjoniana, and ultima and can find no detail that would distinguish one from another."…”

Identification is even more difficult with post cranial bones and is compounded by breakage as typifies archaeological deposits, and so specimens are often grouped into large, medium and small size groupings within genera (e.g., Murphy and Pennoyer, 1952;Walker et al, 1990;Wragg, 1995;Olson and Rasmussen, 2001;Cooper and Tennyson, 2008;Tennyson et al, 2015).…”

“…Given the diversity of similar-sized taxa either occurring or likely to have occurred in the Gambier Group region, we adopt a conservative approach and identify bones to genus and size categories as follows using the term magn. from the Latin magnitudino to indicate the approximate size of the bones in question without implying possible relationship, following Olson and Rasmussen (2001): Puffinus magn. P. bailloni (to include all small Puffinus taxa); Pterodroma magn.…”

This paper analyses 647 bird bones identifiable at least to family-level collected from archaeological sites in 2005, 2012 and 2014 by P. Kirch, in the Gambier Group, French Polynesia. The bones derive from Onemea Site (TAR-6) on Taravai Island, Nenega-Iti Rock Shelter (AGA-3) on Agakauitai Island and Kitchen Cave (KAM-1) on Kamaka Island. Eighteen bird species, four newly recorded in this archipelago, are represented among the bones from archaeological layers dating from human arrival in the tenth century to the late pre-European contact period in the early nineteeth century. They reveal that the original avifauna from the Gambier Group minimally included 37 species. These include six now extinct taxa, a species of Pseudobulweria petrel, two columbids (Bountyphaps obsoleta, Ducula tihonireasini n.sp. described herein) and three other land birds that were recorded historically. Minimally, a further six species have been extirpated from the Gambier Group. These archaeological avifaunas are strongly dominated by seabirds (89.4% Minimum Number Individuals) but differences in species representation and dominance suggest the composition of breeding seabird faunas differed between islands. Columbidae were the dominant land birds (58.9% MNI), although no species of this family currently exist on this archipelago.
