This study examines 55 coprolites from the Na Duong Basin to reconstruct the paleoenvironment. Coproecology sheds light on understanding the complex prey-predator relationships, trophic dynamics, and ecosystem evolution. Through quantitative and multidisciplinary analysis, the putative coprolites were attributed to crocodilian producers, leading to...

The Çorakyerler fossil locality in Anatolia reveals unique faunal elements. This study introduces Hystrix kayae sp. nov., a new Late Miocene porcupine initially classified as Hystrix sp. Yavuz et al., 2018. This finding expands our knowledge of Late Miocene Anatolian porcupines, bringing the total number of known species to three. H. kayae sp. nov....

A rare ichnological example of a crocodilian footprint on an Eocene crocodilian coprolite has been discovered. The enigmatic specimen, measuring 4 cm in length, was found among 100 coprolites at the Na Duong coal mine in Lang Son province, northern Vietnam. Almost all the discovered coprolites were ascribed to a potential crocodilian producer, sugg...

In this paper, seven coprolites from the Lower Cretaceous of Tsagan-Tsab formation have been described. Thus, producing a significant contribution to what we perceived as the first detailed study of coprolites from the Mesozoic deposits in Mongolia. The collected coprolites encompass a total of six spiral amphipolar and one scroll coprolites. We pr...

This study introduces Hystrix aegeanensis n. sp., a new late Miocene (MN 12) porcupine species from Samos, Greece, and Karaağaç, Türkiye. This represents the fifth record of late Miocene Hystrix from Europe and Asia Minor. H. aegeanensis n. sp. exhibits a unique occlusal outline and pattern compared to those of all other late Miocene Hystrix specie...

This study reconstructs the Early Pleistocene paleoenvironment of the Yuanmou Basin through coproecology of the third member of the Yuanmou Formation. We examined 38 exceptionally well-preserved coprolites from a new fossil locality, and attributed the putative defecating agent to the hypercarnivorous diet canid, Sinocuon yuanmouensis through geoch...

Porcupines, members of the Hystricidae family, represent a unique group of herbivorous mammals. This study details the identification of a newly discovered mandible fragment of Hystrix primigenia, along with a right cheek tooth series from the middle Turolian Kemiklitepe-A fossil locality. While Hystrix fossils are found in numerous localities, the...

This study reconstructs the Early Pleistocene paleoenvironment of Yuanmou Basin through coproecology of the third member of the Yuanmou Formation. We examined 38 exceptionally well-preserved coprolites from a new fossil locality, and attributed the putative defecating agent to the spectacular hypercarnivorous diet canid, Sinocuon yuanmouensis throu...

Reconstructing the paleoenvironment of Na Duong Basin by using coproecology is significant in understanding the intensive prey-predator relationships, the tropic relationship and the ecosystem evolution within the paleo-locality. A total of 55 measurable coprolites (IVPP V 27941/1 till IVPP V 27491/55) and numerous coprolite fragments from Na Duong...

Özlüce Fossil vertebrate locality is located 1km north of Özlüce Village which is located about 35 km NW of Muğla. The excavations and field surveys were conducted in 1993 under the scientific consultation of Prof. Dr. Berna Alpagut, together with Muğla Museum Directorate. The excavations had started in 1994 with the financial support and authoriza...

The Coronavirus 19 (SARS-CoV-2) protracted health crisis has led to the restrictions of human mobility around the world, which ultimately created rare sightings of wildlife activities in public areas. In this paper, we reveal the occurrences of an otter family on the shores of Abbas beach, located in Tanjung Bungah at the north of Pulau Pinang, Mal...

Seven coprolites from the Lower Cretaceous of Tsagan-Tsab formation have been described, thus making this paper a significant contribution to the study of the firstly recorded coprolites from the Mesozoic deposits in Mongolia. The collected coprolites comprised a total of five morphotypes, whereby six of them are considered to be spiral amphipolar...

Kemiklitepe is a well-known locality with four recognised fossiliferous horizons, KTA to KTD, which have yielded a plethora of mammalian remains. Previous taxonomic studies indicate the presence of three giraffid taxa: Samotherium major and Palaeotragus rouenii from the uppermost three horizons, KTA, KTB and KTC, as well as Palaeotragus rouenii and...

Two new small mammal assemblages from the abandoned Harami lignite mine, as an addition to previously known Harami assemblages, provide a better insight in the palaeoenvironments in Anatolia in local Biozone C (MN 2, early Miocene). Based on the new material, the Eumyarion assemblages are considered to consist of three, rather than two species, in...

Terrestrial fossil records from the SW Anatolian basins are crucial both for regional correlations and palaeoenvironmental reconstructions. By reassessing biostratigraphic constraints and incorporating new fossil data, we calibrated and reconstructed the late Neogene and Quaternary palaeoenvironments within a regional palaeogeographical framework....

The fossiliferous site at Kavakdere is one of many important late Miocene fossil mammal-bearing localities in Anatolia. Previous taxonomic studies on its fauna have revealed a plethora of taxa. However, the fossil Giraffidae from this early Turolian locality were until now poorly documented. New comprehensive descriptions, comparisons and metric an...

By reassessing biostratigraphic constraints and incorporating new fossil data, we calibrated and reconstructed the late Neogene and Quaternary palaeoenvironments within a regional palaeogeographic framework.

Alcicephalus neumayri is a large-sized giraffid, which is mostly known from its type locality, Maragheh, Iran. The taxon has also been reported from North China and it is in fact the most abundant giraffid known from the eastern outskirts of the Pikermian biome. Reassessment of previously studied material from the fossiliferous site at Kavakdere, r...

Uşak - Karabeyli, which is the name of the rich fossil mammalian locality was discovered in the Late Miocene Asartepe formation near the town of Uşak, Western Anatolia during late 1990’s. The preliminary faunal list comprises 7 genus and species of: AVES: Struthio; CARNIVORA: Ictitherium cf. viverrinum; PROBOSCIDEA: Choerolophodon sp.; PERISSODA...

The survey project on Neogene and Quaternary fossil localities of Burdur has been conducted by one of the authors (FAD) since 2010 with the permission granted by the Ministry of Culture and Tourism leading the discovery of some new Plio-Pleistocene fossil sites including Yassıgüme and Kocakır-2 in province of Burdur where Kocakır-1 locality was alr...

The “Lignite Deposit Exploration in Turkey” project, conducted by a group of German and Turkish geologists, led to the discovery of the “Paşalar Hominoid Site” in 1969. The first excavations in Paşalar were carried out by H. Tobien and his team and the preliminary results of the faunal list, which included 47 micro and macromammalian taxa, were pub...

Three rich fossil mammalian localities were found, covering approximately 7000 m2 area on the northern flank of Kaklıca Hill, 1km north of Özlüce Village which is located at the Yılanlı site, about 35 km NW of Muğla. The excavations and field surveys were conducted in 1993 under the scientific consultation of Prof.Dr.Berna Alpagut, together with Mu...

Gebeceler Formation, which indicates Middle Miocene continental deposition around the Afyon region, is composed of alluvial deposits at its base and grades upward into volcanosedimentary lacustrine sediments. Reaching the thickness of up to 170 m in the study area, the Gebeceler Formation is composed of synsedimentary volcanoclastic units of " Afyo...
