From the album: Fossils
1.5 inch lamnid type shark vertebra in matrix from the New Bern quarry. Not sure if this is from the Oligocene River Bend Formation or the Eocene Castle Hayne Formation. If you think you recognize which formation this is from, leave a comment. -

Help me understand the River Bend Formation and the age of H.serra in North Carolina
DevilDog posted a topic in General Fossil Discussion
I have been researching why my specimens of H.serra teeth from Topsail Island and Lee Creek look different. Apparently, H.serra from the early Oligocene are smaller, less robust, and have finer serrations compared to later, Miocene H.serra teeth. Is my conclusion accurate? The H.serra from Topsail Island are supposedly from the River Bend Formation. There is conflicting information on the internet about the age of this formation. Some sources say "early" or "lower" Oligocene, some say "middle-late" Oligocene. Which is correct? If "early" is correct, when was it formed? Closer to 33 mya or more recent? For H.serra found in North Carolina, what is the range in age? Oligocene-Miocene /33.9-5.3 mya? Is it possible to narrow down that range more accurately? -
