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. [4]
