Fossil Equus are usually associated to open grasslands and considered specialist feeders (grazers) that occupied similar niches throughout the Pleistocene, albeit it has been observed that taxa can display more generalist diets and even occupy less open habitats (Strani et al., 2019; Saarinen et al., 2021). During the Late Pleistocene, two species...

This volume honours Professor Jorge Morales – one of the world´s leading experts in fossil carnivorans, a great scholar, and inspiration of many to follow him in the discipline of palaeontology – to mark his recent retirement. In July 2021, Prof. Morales retired after 50 years working and building up a reputation not only as a leading scientist but...
Article
Acteocemas, a very poorly documented early Miocene stem-cervid, is one of the first ruminants bearing antler-like appendages, which has provided a ground for discussion on the origin of antlers. We describe a new and very complete appendage from the site of Sant Andreu de la Barca (Spain) together with some other unpublished specimens from the near...
Article
Els Casots is one of the richest fossil vertebrate sites of the Vallès-Penedès Basin (Catalonia, Spain). It was discovered in 1989 and excavated briefly during the 1990s, resulting in the recovery of thousands of remains and the erection of several new mammal species. Excavations were resumed in 2018 and continue to date. Here we provide updated re...
Article
The fossil record of lynxes provides clear evidence of a large range across the North Hemisphere during the Pliocene and Pleistocene. However, their origin, systematics and evolutionary relationships are still fraught with difficulties and controversy. Here we report a complete hemimandible of a medium-sized felid from the Early Pleistocene (MN17,...
Article
Small to medium-sized mustelids from the last 18 million years represent a heterogeneous group of carnivorans with a wide-ranging record in the northern hemisphere. They were first referred to the genera Mustela and Martes, but lately ascribed to the latter, and hence considered as the longest-lived genus within Mustelidae. However, a great many of...

Venta Micena is an area containing several palaeontological sites marking the beginning of the Calabrian stage (Early Pleistocene). The richness of the fossil accumulation including species of Asian, African and European origin, makes Venta Micena a key site for the the palaeoecological and palaeoenvironmental study of southern Europe during the Ea...
Article
The intra-montane Guadix-Baza Basin is one of the few continental basins in Europe that hosts a well-dated set of fossiliferous sites spanning from the latest Miocene to the late Middle Pleistocene. The Cúllar de Baza 1 (CB-1) represents a key site to investigate the effects of the Early-Middle Pleistocene Transition, considered a fundamental trans...
Conference Paper
Full-text available
Despite lynxes were spread throughout Europe, Asia and North America during the Pliocene and Pleistocene, their origin is still far from being understood and some controversy exists about their evolutionary relationships. Here we report and describe a new complete left hemimandible of a medium-sized felid from the Early Pleistocene (MN17, middle Vi...
Article
Full-text available
Background The two main primate groups recorded throughout the European Miocene, hominoids and pliopithecoids, seldom co-occur. Due to both their rarity and insufficiently understood palaeoecology, it is currently unclear whether the infrequent co-occurrence of these groups is due to sampling bias or reflects different ecological preferences. Here...

Full-text available
There has been little discussion about the relationship between geoethics and geological heritage, probably because both topics are relatively new in geosciences and still little understood. Here we provide a short overview of the relevant concepts of geodiversity, geological heritage and geoconservation. Palaeontological heritage is specially high...

Article
Although extensive research has been carried out in recent years on the origin and evolution of human bipedalism, a full understanding of this question is far from settled. Miocene hominoids are key to a better understanding of the locomotor types observed in living apes and humans. Pierolapithecus catalaunicus, an extinct stem great ape from the m...
Article
Lophocyonids are one of the more enigmatic groups of Carnivora in the European Miocene fossil record. Lophocyonids are clearly distinguished from other Feliformia by their peculiar lophodont dental morphology. For this reason, the systematic relationships of the family have been controversial. Here we describe and interpret dental remains from the...

The intermontane Anagni Basin (Frosinone, central Italy) is an important region for Italian biochronology and paleoecology due to the presence of two rich fossil assemblages dated to the Early (Coste San Giacomo) and Middle Pleistocene (Fontana Ranuccio). These sites have yielded a vast collection of large fossil mammals with a well-documented pres...
Article
The Early-Middle Pleistocene Transition (EMPT) (ca. 1.4–0.4 Ma) represents a fundamental transformation in the Earth's climate state, starting at 1.4 Ma with a progressive increase in the amplitude of climatic oscillations and the establishment of strong asymmetry in global ice volume cycles. The progressive shift from a 41kyr–100kyr orbital rhythm...
Conference Paper

Mastication of dietary items with different mechanical properties leaves distinctive microscopic marks on the surface of tooth enamel. The inspection of such marks (dental microwear analysis) is informative about the dietary habitus in fossil as well as in modern species. Dental microwear analysis relies on the morphology, abundance, direction, and...

El Antropoceno, la actual etapa de la Historia de la Tierra, comenzó en el siglo dieciocho, con el comienzo de la Revolución Industrial. La definición de este inicio se basa en los niveles crecientes de dióxido de carbono y metano desde esa época(Crutzen 2016). Después de tres siglos, y teniendo en cuenta el desarrollo exponencial científico y tecn...
Article
Climatic oscillations at the Gelasian/Calabrian transition modified terrestrial palaeoenvironmental settings in the European region. A gradual drop in global temperatures beginning about 2.7 Ma led to drier conditions and to a reduction in, and subsequent disappearance of, sub-tropical vegetation in the central Mediterranean area by ca 1.2 Ma. Larg...

Deer are an iconic group of large mammals that originated in the Early Miocene of Eurasia (ca. 19 Ma). While there is some consensus on key relationships among their members, on the basis of molecular- or morphology-based analyses, or combined approaches, many questions remain, and the bony labyrinth has shown considerable potential for the phyloge...

Full-text available
Dental microwear analysis on the tooth surface has been widely employed for the reconstruction of the feeding behaviour and tooth use in both extant and fossil vertebrate taxa. This approach relies on the microscopic scars present on the dental enamel left by ingested foods during the last few meals of the animal, providing information about short-...

The Vallès-Penedès Basin is a classical area for the study Miocene terrestrial faunas of Europe. However, in comparison to the middle and late Miocene part of the record, the early Miocene has deserved little attention. Indeed most of the currently known sites were discovered more than 60 years ago and have not been systematically sampled again. Ne...
Article
Resource competition and niche partitioning among the exceptionally high number of sympatric ungulates of the Early Pleistocene site of Coste San Giacomo (Central Italy) is here examined through the study of their dietary proclivities and body size. The main aim of this study is to investigate the niche differentiation mechanisms that let the fossi...

The Vallès-Penedès Basin is a classical area for the study of the Miocene terrestrial faunas of Europe. However, in comparison to the middle and late Miocene part of the record, the early Miocene has received less attention. Indeed, most of the currently-known sites were discovered more than 60 years ago and have not been systematically sampled sin...
Article
The Valles-Penedes Basin (Catalonia, Spain) is classical area for the study of Miocene land mammal faunas. Nevertheless, the early Miocene part of the record has deserved little attention as compared to younger intervals. Most notably, the small mammals of this age have not been described in detail, consequently hampering the correlation of the Val...
Conference Paper
The knee plays a central role for primate locomo- tion since it participates in body weight bearing, propulsion and support. Living non-human homi- noids show a versatile knee that allows them to rely on a varied and non-stereotyped set of joint movements during orthograde behaviors. In this regard, studying the Miocene primates becomes essential t...
Article
Although the initial formulation of modern concepts of adaptive radiation arose from consideration of the fossil data, rigorous attempts to identify this phenomenon in the fossil record are largely uncommon. Here I focus on direct evidence of the diet (through tooth-wear patterns) and ecologically-relevant traits of one of the most renowned fossil...
Article
Deer (Cervidae) have a long evolutionary history dating back to the Early Miocene, around 19 million years ago. The best known fossils to document this history belong to European taxa, which all bear cranial appendages more or less similar to today's deer antlers. Despite the good fossil record, relationships of the earliest stem deer and earliest...

Natural selection in isolated environments led to the positive selection of species bearing an extraordinary array of morphological traits and a very high grade of endemism. The unbalanced mammal assemblage found in the Upper Miocene karst infillings of the Gargano Peninsula (southern Italy), and especially the intriguing ruminant Hoplitomeryx, is...
Conference Paper
Full-text available
The Early Pleistocene is considered to be a time of important extinctions and faunal dispersals among the European large mammalian communities. We analysed tooth wear patterns and molar crown height (or hypsodonty) of herbivore ungulates of the rich mammal assemblage of the Early Pleistocene site of Coste San Giacomo (central Italy), dated around 2...

Meet your gibbon cousin Apes are divided into two groups: larger-bodied apes, or hominoids, such as humans, chimps, and gorillas; and smaller-bodied hylobatids, such as gibbons. These two lineages are thought to have diverged rather cleanly, sharing few similarities after the emergence of crown hominoids. Alba et al. describe a new ape from the Mio...
Article
The land mammal record of the Vallès-Penedès Basin (Catalonia, NE Spain) ranges fromthe early Miocene (Ramblian) to the late Miocene (Turolian), that is from about 20 to 7 Ma.Here we present an updated review of the mammal succession focusing on biochronologyas well as on environmental and faunal changes. Based on faunal similarities with centralEu...
Article
Quaternary glacial/interglacial alternations, influenced by orbital obliquity cycles with a 41-ka long periodicity, started in the northern hemisphere around 2.6 Ma ago. Such alternations affected the terrestrial ecosystems, especially those of the Mediterranean region, with changes in the floristic communities and the dispersal and radiation of a...

The vertebrate locality of Venta del Moro constitutes one of the more remarkable sources of information for the latest Miocene continental record of western Europe. Its unique cosmopolitan assemblage, dated at 6.23 Ma (Ventian, biozone MN13, local zone M3), furnishes evidence of faunal dispersal from Africa and Asia to Europe during the latest Mioc...
Article
Mammals of numerous lineages have evolved high-crowned (hypsodont) teeth particularly during the last 20 million years. This major phenotypic change is one of the most widely studied evolutionary phenomena in a broad range of disciplines, though the mechanisms underlying its transformation remain unresolved. Here, we present the first Finite Elemen...

Given the central adaptive role of diet, paleodietary inference is essential for understanding the relationship between evolutionary and paleoenvironmental change. Here we rely on dental microwear analysis to investigate the role of dietary specialization in the diversification and extinction of Miocene hominoids from Western Eurasian between 14 an...
Article
Full-text available
Global climate shifts and ecological flexibility are two major factors that may affect rates of speciation and extinction across clades. Here, we connect past climate to changes in diet and diversification dynamics of ruminant mammals. Using novel versions of Multi-State Speciation and Extinction models, we explore the most likely scenarios for evo...

The potential of Finite Element Analysis (FEA) as an analytical technique in biological research has been widely highlighted in recent years. In spite of its great power, only in the best of circumstances one can compare the behaviour of models that differ in size and shape. Here, a new and easy procedure to scale FE models of plane elasticity is p...
Article
Key innovations are newly acquired structures that permit the performance of a new function and open new adaptive zones, and are therefore of paramount significance for understanding the history of the Ruminantia -particularly its diversification through the Miocene. Here we review and discuss what is known about these evolutionary novelties, with...

Article
Pliopithecinae and Crouzeliinae (Primates: Pliopithecidae) are distinguished dentally by the sharper crests, more compressed cusps, larger foveae, and narrower molars of the latter. Traditionally, such differences were qualitatively related to increased folivory in crouzeliines. This was subsequently disproved by microwear and shearing crest analys...
Conference Paper
Quantifying the kinematics of the patella is essential for understanding the role of the knee joint in locomotion, but also a challenge due to the complexity of function of the muscles and ligaments around the joint. Previous studies focusing on the human knee have postulated two different biomechanical models for the patella, the short-beam and th...
