The Late Miocene fossil locality Pécs-Danitzpuszta (Mecsek Mts., Hungary) has yielded cranial and postcranial bones of giant salamanders. Based on taxonomical studies, these relatively well-preserved, isolated bones belong to the cryptobranchid species Andrias scheuchzeri. Whereas the species is well documented from Neogene of Central Europe, this is the first record of the genus Andrias from Hungary, representing the sole record of giant salamanders from the country. The fossils were found in Upper Miocene sands deposited in the brackish Lake Pannon, but their late Miocene age is uncertain, because they occur together with vertebrate remains reworked from older sediments. The mild and humid climate and the presence of freshwater wetlands on the mainland indicated by the fossil flora, the syn-depositional uplift of the mountains providing for a rugged topography, and the intense clastic sediment input into Lake Pannon indicative of a fluvial network on the Mecsek Island and of sufficient precipitation support that conditions were convenient for the giant salamanders in the early late Miocene. Together with three other late Miocene localities in Austria, the Pécs-Danitzpuszta site is the fourth Miocene occurrence of Andrias in the Pannonian Basin System. It resembles the first three localities in lying at the foot of elevated terrain and in having freshwater input, conditions thought to be necessary for giant salamander habitats.

来自Mecsek山脉中新世的巨型sal(匈牙利西南Pécs-Danitzpuszta)

中新世晚期化石产区Pécs-Danitzpuszta(匈牙利Mecsek山)已产生了巨型sal的颅骨和颅后骨。根据分类学研究,这些相对保存完好的分离出的骨头属于隐性分支物种Andrias scheuchzeri。尽管该物种已从中欧新近纪实记录下来,但这是安德里亚斯(Andrias)属的第一个记录。来自匈牙利,代表该国巨型giant的唯一记录。这些化石是在咸淡的潘农湖中沉积的中新世上层砂岩中发现的,但是它们的中新世晚期尚不确定,因为它们与从较旧沉积物中返工的脊椎动物遗骸一起出现。化石植物群表明大陆上温和湿润的气候和淡水湿地的存在,山脉的同沉积沉积抬升提供了崎top的地形,并且大量的碎屑沉积物输入到潘农湖,表明该湖上有河流网络。麦切克岛(Mecsek Island)和充足的降水支持使中新世晚期晚期的sal非常便利。Pécs-Danitzpuszta站点与奥地利其他三个中新世晚期地点一起,是第四次中新世。潘诺尼亚盆地系统中的安德里亚斯。它与前三个地方相似,位于高地的山脚下,有淡水输入,这被认为是巨型giant栖息地所必需的条件。
