“…(2008b) in the temnospondyl part of the cladogram is that albanerpetontids are placed outside Batrachia (frogs and salamanders) and that they are not the sister group of Caudata. This position of albanerpetontids is in agreement with Gardner (2001). Our results corroborate the monophyly of Karauridae and confirm the previous placement of Karauridae as the sister group of crown‐group salamanders (Urodela; Milner, 1994; Gao & Shubin, 2003; Evans et al ., 2005).…”

The cranial anatomy of the stem salamander Kokartus honorarius, from the Middle Jurassic of Kyrgyzstan, is redescribed in detail on the basis of all available material using conventional methods and high-resolution computed microtomography. In contrast to previous interpretations, the skull is characterized by posteriorly positioned external nostrils, the presence of an internarial fenestra between the premaxillae, the maxillae are not shortened, the overlapping of the frontal by the nasal and the parietal by the frontal, a dentate vomer, a dentate pterygoid with a long, strongly arcuate and anteromedially orientated anterior process, the absence of a fontanelle between frontals and pineal pit on the ventral surface of the frontals, and an inferred unique attachment of the adductor mandibulae internus to the lateral border and ventral ridge of the frontals and parietals. Kokartus is closely related to Karaurus and both these taxa constitute the monophyletic taxon Karauridae, which forms the sister group of crown-group salamanders (Urodela). Karaurids were neotenic forms and neoteny was probably the ancestral life history strategy of salamanders. The morphological analysis of Kokartus supports the current phylogenetic hypothesis that Permian amphibamids (including branchiosaurids) are the closest relatives of salamanders amongst known non-lissamphibian temnospondyls.

“…With the exception of crocodyliforms, all other European groups affected by high extinction rates (squamates, mammals, dinosaurs) are exclu sively terrestrial, whereas among crocodyliforms both terrestrial (atoposaurid) and aquatic (hylaeochampsid) taxa were eliminated. Conversely, amphibians – including predominantly aquatic (batrachosauroidids, discoglossids, palaeobatrachids) or secretive (albanerpetontids; Gardner 2001 ; Gardner and Böhme 2008 ; Maddin et al 2013 ) forms – show high rates of survival, again similar to the pattern described for North America (e.g., Sheehan and Fastovsky 1992 ; Wilson et al 2014b ).…”

The Late Cretaceous was a time of tremendous global change, as the final stages of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to marked paleogeographic and faunal changes, before the end-Cretaceous bolide impact. The terrestrial fossil record of Late Cretaceous Europe is becoming increasingly better understood, based largely on intensive fieldwork over the past two decades, promising new insights into latest Cretaceous faunal evolution. We review the terrestrial Late Cretaceous record from Europe and discuss its importance for understanding the paleogeography, ecology, evolution, and extinction of land-dwelling vertebrates. We review the major Late Cretaceous faunas from Austria, Hungary, France, Spain, Portugal, and Romania, as well as more fragmentary records from elsewhere in Europe. We discuss the paleogeographic background and history of assembly of these faunas, and argue that they are comprised of an endemic ‘core’ supplemented with various immigration waves. These faunas lived on an island archipelago, and we describe how this insular setting led to ecological peculiarities such as low diversity, a preponderance of primitive taxa, and marked changes in morphology (particularly body size dwarfing). We conclude by discussing the importance of the European record in understanding the end-Cretaceous extinction and show that there is no clear evidence that dinosaurs or other groups were undergoing long-term declines in Europe prior to the bolide impact.

“…The distribution patterns identified for the extant taxa are also confirmed by the latest known occurrences in extinct ones. Animal and plant groups that were already distinct at the end-Triassic, but were only lost after the end-Cretaceous mass extinction include the Bennettitales 20 , Albanerpetonidae 21 , and possibly the Meiolaniidae 22 . Their occurrences confirm the refugial function of both the large northern landmasses and the lesser southern continents and islands (e.g., Australia, New Caledonia).…”

Global hotspots in the present-day distribution of ancient animal and plant lineages

The current distribution of biotic lineages that emerged in the deep time has both theoretical and practical implications, in particular for understanding the processes that have forged present-day biodiversity and informing local and regional-scale conservation efforts. To date however, there has been no examination of such patterns globally across taxa and geological time. Here we map the diversity of selected extant seed plant and tetrapod vertebrate lineages that were already in existence either in the latest Triassic or latest Cretaceous. For Triassic-age linages, we find concentrations in several regions – both tropical and temperate – parts of North America, Europe, East and South-east Asia, northern South America, and New Zealand. With Cretaceous-age lineages, high values are relatively uniformly distributed across the tropics, with peak the values along the Andes, in South-east Asia and Queensland, but also in the temperate Cape Mountains. These patterns result from a combination of factors, including land area, geographic isolation, climate stability and mass extinction survival ability. While the need to protect many of these lineages has been long recognised, a spatially-explicit approach is critical for understanding and maintaining the factors responsible for their persistence, and this will need to be taken forward across finer scales.
