Nektognathus evasmithae is an extinct species of nectocaridid that lived about 520 million years ago, in the Cambrian. Its fossils are known from the Sirius Passet Lagerstätte in Greenland, and it was first described in 2025. Nektognathus shares features with both the formerly enigmatic Nectocaris with the stem-chaetognath Timorebestia, suggesting they are closely related.[1]
