Microvertebrates from the Silurian–Devonian boundary beds of the Eastport Formation, Maine, eastern USA
Agnathan and gnathostome remains, associated with lingulid brachiopod fragments and distinctive ostracods, have been extracted from a small calcareous mudstone sample collected from the type section of the Eastport Formation on the northern shore of Moose Island, Maine. The vertebrate assemblage inc...
