Occurrence of the European extinct cordylid genus ‘Bavaricordylus’ from the early middle Miocene of Switzerland was recently questioned. Reanalysis of the Swiss material supports its assignment to the lacertid genus Janosikia, the presence of which is, therefore, indicated for the first time outside from southern Germany. Based on dentary morphology, it seems that two Janosikia morphotypes were present in the Miocene, one with a smooth and a second with a rough lateral surface of the dentary. The lacertid genus Janosikia seems to be confined to Central Europe, thriving there through at least the first half of the Miocene (from ca. 22 Ma to ca. 15.7 Ma).

对来自瑞士的环蜥蜴遗骸的重新解释记录了德国以外首次出现的蜥蜴

来自瑞士中中新世早期的欧洲已灭绝的堇菜属“ Bavaricordylus ”的出现最近受到质疑。对瑞士材料的重新分析支持将其归属于蜘蛛纲Janosikia,因此首次表明其存在于德国南部之外。根据牙齿形态,似乎在中新世存在两种Janosikia形态类型,一种具有光滑的牙齿侧面,另一种具有粗糙的侧面。蜘蛛纲Janosikia似乎仅限于中欧,至少在中新世的前半段(从大约 22 Ma 到大约 15.7 Ma)在那里繁衍生息。
