The earliest Osprioneides kampto borings were found in bryozoan colonies of Sandbian age from northern Estonia (Baltica). The Ordovician was a time of great increase in the quantities of hard substrate removed by single trace makers. Increased predation pressure was most likely the driving force behind the infaunalization of larger invertebrates such as the Osprioneides trace makers in the Ordovician. It is possible that the Osprioneides borer originated in Baltica or in other paleocontinents outside of North America.
最早的奥斯普里翁奈德钻孔发现于爱沙尼亚北部(波罗的海地区)桑德阶的苔藓虫群落中。奥陶纪是单个痕迹制造者清除的硬底物数量大幅增加的时期。捕食压力的增加很可能是奥陶纪大型无脊椎动物(如奥斯普里翁奈德痕迹制造者)内栖生物化背后的驱动力。奥斯普里翁奈德钻孔者有可能起源于波罗的海地区或北美以外的其他古大陆。
