Coleoloides, or the coleolids, are a genus of Cambrian small shelly fossils with an aragonite skeleton.
[1] They were first described in 1889 by Charles Doolittle Walcott as members of the pteropods.
[2] Their affinity is unknown but they were probably produced by an organism of the annelid grade of complexity.
[3]: 37 Calcium carbonate fossils of coleolids have been found at Newfoundland clustered together, oriented vertically.
