Short summary
We describe an unusual millimetre-long tube that was discovered in sediment from the deep sea floor. The tube was made by a single-celled organism by cementing together sedimentary grains from its environment. The specimen is unusual because it implies that the organism used a very high degree of discrimination in selecting its grains, as they are all of one type and most are oriented the same way. It raises intriguing questions of how the organism accomplished this activity.
