In this paper, we have re-examined and assessed the only existing shells of two interspecific hybrid tortoises of Testudo horsfieldii and Testudo h. hermanni from the Walter Kirsche collections. It is the first detailed examination and measurements of important preserve shells of hybrid tortoises of Testudo taxa. An overview of the systematic relationship and the literature debate is given.  Â

Fossil remains of turtles were discovered in various localities of Lower to Upper Miocene within the western part of Turkey. We revised the taxonomic position and describe the systematic paleontology, distribution, phylogeny and palaeo-environments of two Neogene taxa Titanochelon kayadibiensis sp. nov. and Protestudo bessarabica (Testudinidae) of Western Turkey and give an updated list of fossil turtles of Turkey which include Trionyx triunguis (ForskÃ¥l, 1775), Mauremys aristotelica Vlachos et al, 2019, Testudo marmorum Gaudry, 1862, Protestudo bessarabica Riabinin, 1918 and Titanochelon kayadibiensis sp.nov. Â

Nazca is a city and system of valleys on the southern coast of Peru. The name is derived from the Nazca culture, which flourished in the area between 100 BC and 800 AD. Nazca Lines contain over 800 straight lines, 300 geometric figures and 70 biomorphic designs. Some of the straight lines are 30 miles long, while the largest bio morphs stretch up to 1200 feet. Among the zoomorphic figures are the famous Nazca condor, hummingbird, pelican, shark, bird, fish, spider, lizard, parrot, flamingo, iguana, dog, llamas, jaguar, fox, whale and monkey. We have identified a studied figure of Nazca Pampas as a species of umbrella birds (Cephalopterus) and this geoglyph has more resemblances with the short-lobed parasol (Cephalopterus ornatus) than any other species.

Taphonomy and contextual zooarcheology of the first Mesolithic hunting station in Thuringia, Central-Germany (Central Europe) was the study area of this paper. The new site at Göttern is of special importance as it is the first excavated hunting station in Thuringia. Until now, we have depended upon numerous discoveries of surface finds, special single finds and a few burials, for the exploration of the Mesolithic Era. Bone remains of wild boar/pig, red deer, moose, roe deer, aurochscattle, wild horse, brown bear, wolf/ dog, mouse and birds have been discovered. Â
