在北方沙捞越、文莱和沙巴的中新世贝拉特组中发现了Lundgren蛇形虫的洞穴，这里描述为OphiomorphaLundgren.遗迹种在纳闽岛还发现了两种HäntzscheliniaVialov。第三种类型的结构是在文莱发现的，它可能代表了一种未知的板鳃类动物的铸件。洞穴和铸件是在微咸水环境中形成的，可能是在海湾或三角洲的沿岸的区域。
In the Miocene Belait formation of northern Sarawak, Brunei and Sabah burrows ofOphiomorphaLundgren were found, described here asOphiomorpha borneensis n. ichnosp. A few associated spiral tunnels of theXenohelix-type were also found. Two species ofHäntzscheliniaVialov occurred on Labuan Island. A third type of structure was found in Brunei and it probably represents castings of an unknown lamellibranch. The burrows and castings were made in a brackish water environment, probably in the littoral zone of an embayment or delta.
