DNA and Morphology Unite Two Species and 10 Million Year Old Fossils
Figure 3
Approximate geographic range of A. wilsonae and A. knoxi.
The theoretical extent of the range of these species is indicated by the dotted line. A. wilsonae generally occupies depths from 50 m to 450 m and A. knoxi is found between approximately 400 and 750 meters. Approximate locations of sample sites of the DNA sequenced specimens are indicated with circles, boxes indicate the locations of samples only used for morphometric analysis. Inset – A sample of the morphological variation of A. wilsonae (A) M190111, (B) M190079, (C) M177177, and the A. knoxi form (D) 30037. The sampling locations of these specimens are indicated with the corresponding lower case letter.
