Abstract An insect boring of unique shape is described from a lignitic layer within the Early Cretaceous (Berriasian) Skyttegård Member of the Rabekke Formation on Bornholm. Morphologically it cannot be compared to any modern or fossil wood borings, although some structures are reminiscent of Scolytidae, Platypodidae and Lymexylonidae. Most probably, however, the tracemaker was a female fungus-farming beetle, thus producing an agrichnion.

在丹麦博恩霍尔姆的早白垩世木材中钻孔的昆虫

摘要 描述了博恩霍尔姆岛 Rabekke 地层早白垩世（贝里亚斯）Skyttegård 段的褐煤层中的一种形状独特的昆虫钻孔。从形态上讲，它无法与任何现代或化石木钻孔相提并论，尽管有些结构让人联想到 Scolytidae、Platypodidae 和 Lymexylonidae。然而，最有可能的是，示踪者是一只雌性真菌养殖甲虫，因此产生了 agrichnion。
