A fairly preserved ammonite of Early Cretaceous age from the Mecsek Mountains, southern Hungary is described. Tescheniceras subpachydicranum is the first record of late Valanginian ammonites from the Mecsek tectonic zone from a previously unknown locality indicating the uppermost Valanginian Criosarasinella furcillata Zone. This is the first ammonite-supported evidence for the presence of upper Valanginian strata in the Mecsek Mountains that stretches the time-span of the continuous basinal sedimentation from the beginning of the Berriasian till the Valanginian. The new finding raises the possibility for the presence of the Hauterivian strata too, which was never recognised by ammonites.

描述了来自匈牙利南部 Mecsek 山脉的一种保存完好的早白垩世菊石。Tescheniceras subpachydicranum是来自 Mecsek 构造带的晚期 Valanginian菊石的第一个记录，来自一个以前未知的地方，表明最上面的 Valanginian Criosarasinella furcillata 带。这是 Mecsek 山脉上瓦兰吉阶地层存在的第一个菊石支持的证据，该地层延长了从贝里亚阶开始到瓦兰吉阶的连续盆地沉积的时间跨度。新发现也提出了 Hauterivian 地层存在的可能性，而菊石从未发现过这种地层。
