Coryphaenoides richi sp. nov. (Macrouridae, Teleostei) from the deep-marine, Oligocene Makah Formation of Washington State, U. S. A.

This dataset contains the digitized treatments in Plazi based on the original journal article Schwarzhans, Werner W., Moritz, Timo, Goedert, James L. (2026): Coryphaenoides richi sp. nov. (Macrouridae, Teleostei) from the deep-marine, Oligocene Makah Formation of Washington State, U. S. A. Zitteliana 100: 31-38, DOI: 10.3897/zitteliana.100.182311AbstractSilicified scales, bones and one otolith were extracted with mild acid solution from a small carbonate concretion found in the Makah Formation on the south shore of the Strait of Juan de Fuca, Washington State, U. S. A. The strongly-spiny scales are typical for fishes of the family Macrouridae and the otolith facilitates the identification and description of a new species of the genus Coryphaenoides, C. richi sp. nov. The Makah Formation was deposited in a deep-marine outer-fan environment during the early Oligocene. The discovery of Coryphaenoides richi in such an environment is testimony for an effective population of the deep sea with macrourid fishes and that the genus Coryphaenoides was firmly established in the early Oligocene.
