Nektognathus
Nektognathus evasmithae (IPA:) is an extinct species of nectocaridid that lived about 520 million years ago, in the Cambrian. Its fossils are known from the Sirius PassetLagerstätte in Peary Land, Greenland, and it was first described in 2025. Nektognathus shares features with both the formerly enigmatic Nectocaris and with the stem-chaetognathTimorebestia, suggesting they are closely related.
