“…The new Tarsius species was discovered through surface survey, and it is associated with a diversified vertebrate fauna including bony fishes, snakes, turtles, crocodilians and a variety of other mammals such as Stegolophodon [12,13], Gomphotherium cf. browni [14], Gaindatherium [15], Siamogale thailandica [16], Maemohcyon potisati [17], Neocometes cf. orientalis, Prokanisamys benjavuni [18] and Siamoadapis maemohensis [19].…”

Tarsius is an extant genus of primates endemic to the islands of Southeast Asia that is characterized by enormously enlarged orbits reflecting its nocturnal activity pattern. Tarsiers play a pivotal role in reconstructing primate phylogeny, because they appear to comprise, along with Anthropoidea, one of only two extant haplorhine clades. Their fossils are extremely rare. Here, we describe a new species of Tarsius from the Middle Miocene of Thailand. We reconstructed aspects of its orbital morphology using a geometricmorphometric method. The result shows that the new species of Tarsius had a very large orbit (falling within the range of variation of modern Tarsius) with a high degree of frontation and a low degree of convergence. Its relatively divergent lower premolar roots suggest a longer mesial tooth row and therefore a longer muzzle than in extant species. The new species documents a previous unknown Miocene group of Tarsius, indicating greater taxonomic diversity and morphological complexity during tarsier evolution. The current restriction of tarsiers to offshore islands in Southeast Asia appears to be a relatively recent phenomenon.

The vertebrate community of the late Miocene locality of Batallones-1, Madrid Province, Spain, is mainly composed of mammals of the order Carnivora, which represents 98 per cent of the total number of macro-mammal fossils. Here, we describe craniodental remains of approximately 12 individuals of a new, highly specialized member of the Amphicyonidae, previously assigned to Amphicyon sp. cf. A. castellanus. A phylogenetic analysis of Amphicyoninae shows that this new form, named Magericyon anceps gen. et sp. nov., is markedly distinct from all other known Amphicyoninae, specifically in its hypercarnivorous features (strongly compressed upper canines, absence of dP1 ⁄ dp1 and P2 ⁄ p2, single-rooted p3, absence of a metaconid on the lower molars, and reduction of M2 relative to M1).

“…The unit is composed of five mammal-bearing fossiliferous coal layers (I, J, K, Q, and R, from the top to the bottom) (Corsiri and Crouch 1985), which have yielded one of the richest middle Miocene mammalian faunas of Southeast Asia (Table 1) (Koenigswald 1959;Ginsburg et al 1983;Ducrocq et al 1994Ducrocq et al , 1995Peigné et al 2006;Chaimanee et al 2008;Chavasseau et al 2009;Coster et al 2010;Grohé et al 2010;Grohé 2011;Suraprasit et al 2011Suraprasit et al , 2014. The age of the fossil-bearing deposits ranges between 14.2 and 12.0 Ma according to magnetochronological data (Coster et al 2010), with the age of layers which yielded the material described here (K and Q) in particular having been estimated at 13.…”
