The mammal collection of Nikiti 1 (NKT) is relatively poor; it has been already described in a series of publications. During the last field trips in Nikiti (2004–2009), the unearthed material from NKT remained scarce; it is described herein, alongside a revision of the old collection. The newly described material includes some rhinocerotid remains assigned to “Diceros” neumayri and Dihoplus pikermiensis...
In this article, we present the proboscidean assemblage from the upper Miocene vertebrate locality Nikiti 2 (Chalkidiki Peninsula, Macedonia, Greece). Based on the dental remains, the material belongs exclusively to the genus Choerolophodon. The morphology of the dp3/DP3 and the dimensions of the deciduous dentition clearly distinguish the Nikiti 2 choerolophodont from the early Vallesian Choerolophodon anatolicus...
The primates recognized in the fossiliferous sites of Nikiti include hominoids and cercopithecoids. On the one hand, a mandible and a maxilla of a hominoid primate were discovered in the terminal Vallesian (terminal MN 10) locality of Nikiti 1 (NKT). Their morphology and size fit well with the Greek hominoid Ouranopithecus macedoniensis known from the Axios Valley (Macedonia, Greece), an area located...
The upper Miocene avian localities of Greece are rare and the known material is poor. During the last campaigns of excavations in Nikiti 2, a tarsometatarsus of a large struthionid has been unearthed, enriching the poor known Greek sample of late Miocene birds. Morphological and comparative features suggest similarities with the extant and fossil large struthionids referred to Struthio. Several taxa...
A new specimen of Testudo sensu stricto from the late Miocene locality Nikiti 2 (NIK; Macedonia, Greece) is described. It is a small-bodied testudinid very close to the species Testudo marmorum, but it can be differentiated from it by some minor features not observed on the holotype specimen of T. marmorum. It belongs to the group of extant and extinct testudinids that have a hypo-xiphiplastral hinge,...
The skull and some mandibular fragments with deciduous dentition of a chalicothere are studied in the present article. The studied material is described and compared with the known material from other localities of Greece and neighboring areas. The comparisons indicate that the studied material shares morphological and metrical similarities with the well-known ancylothere of Greece, Ancylotherium...
The artiodactyl assemblage of the upper Miocene fossil locality Nikiti 2, Northern Greece, is rediscussed in the light of new data provided by a second, five-year long round of fieldwork. The significantly enriched artiodactyl material allows revising and updating previous systematic interpretations. Along with the previously recorded Helladotherium duvernoyi, Gazella cf. capricornis, and Nisidorcas planicornis,...
Although the Nikiti 2 (NIK) mammal collection is rich in large fossil vertebrates, rhinocerotid's remains are restricted to both tooth rows of a mandible. The teeth are heavily worn and the preservation quite well. The morphology of the teeth indicate close similarities to the horned-rhinoceros“Diceros” neumayri (Osborn, 1900). The metrical comparison of the NIK teeth with the two well-known rhinocerotids...
The fossiliferous sites of Nikiti are located north of the homonymous village at the beginning of the Sithonia Peninsula in Chalkidiki (Macedonia, Greece). The Neogene deposits of Chalkidiki outcrop mainly in its western part and consist of four successive formations: Antonios Fm. (clastic, fluvial; early/middle Miocene – ?Vallesian), Triglia Fm. (fluvio-terrestrial; late Miocene), Trilophos Fm. (marine-brackish;...
The carnivoran sample from Nikiti 2 (NIK) is relatively poor, including a small number of specimens, mainly postcranials. The best-preserved specimen is a skull and mandible, as well as some bones of the common late Miocene hyaenid Adcrocuta eximia. The sample of A. eximia is similar to the subspecies A. eximia eximia from the Turolian of Greece. A second hyaenid species is represented by an upper...
The present study aims to assess the environmental conditions that prevailed during the late Miocene in the vicinity of Nikiti 2, Chalkidiki Peninsula (northern Greece). Here, a Dental Microwear Texture Analysis of three species of equids (20 specimens) and six species of bovids (76 specimens) is combined with analysis of the phytolith content of sediments from Nikiti 2. The latter analysis provided...
Hipparionines represent the greatest part of the Nikiti 2 (NIK) fossil mammal collection. The determination of the material suggests the presence of four distinct species, two small, a medium and a large sized form. The small-sized forms attributed to Hipparion macedonicum, well known in northern Greece, and to H. sithonis nov. species. The weak canine fossa and the retraction of the narial opening...
The study of the new and old collections of the Nikiti vertebrate localities included in this volume provides several new evidences for the taxonomy, composition, chronology and palaeoecology of these late Miocene mammal faunas. The faunal list of both primate bearing localities is enriched and improved by addition of new taxa and revision of older identifications; two new species are recognized in...
More than 1500 sauropod and theropod tracks have been discovered and excavated on the floor of a disused 3800m2 quarry, near the village of Loulle (French Jura). These levels correspond to a tidal-flat environment, from intertidal to supratidal zone, dated from the earliest Kimmeridgian (∼157M.a.). Eighteen sauropod trackways have been recognized, ranging from 3.8m to 51.5m in length. These trackways...
In the late 1960s, rests of a low-diversity flora dominated by the lycopsid Pleuromeia were reported. The specimens were recovered from a creek near San Rafael, Mendoza Province, western Argentina, in the lower section of the Puesto Viejo Group, the Quebrada de los Fósiles Formation, considered as Early Triassic in age. Despite the importance of this flora with respect to the end-Permian mass extinction...
Numerous ascidian spicules are reported for the first time from the lower Sarmatian Darabani-Mitoc Clays of Costeşti, north-western Moldova. The biological interpretation of the studied sclerites allows distinguishing at least three morphospecies (Polysyncraton-like, Trididemnum-like, and Didemnum-like) within the Didemnidae family. Eight other morphological types of spicules are classified as indeterminate...
The trace fossil Macaronichnus segregatis is interpreted to be produced by opheliid polychaetes that feed on epigranular microbes and organic matter commonly abundant in shallow-marine foreshore sands. Resulting traces are horizontal and typically random in orientation, but sometimes perpendicular to the shoreline. However, M. segregatis in Neogene sandy sediments from Santa Maria Island in the Azores...
Neptunian dikes, representing deposit-filling fractures in older rocks, have long attracted the attention of paleontologists because they may provide unique insights into ancient cryptic submarine cave ecosystems. In the epicratonic Poland, fossil-bearing neptunian dikes are especially well known in Upper Jurassic (mainly Oxfordian) strata. However, the age, origin and faunal composition of these...
