My Fossils: Part Two.
In the blog I posted previously, I explained how my partner, two friends, and I went for a hike at Oologa Lake, OK. Only to find fossils on a beach. This is a continuation of the “My Fossils” series, there will be more to come in the future, enjoy.
This first two images are of Rugose or “Horn” Coral. The first image is the first fossil I found. The second is one I found while searching through the tiny rocks on the beach.
Rugose (Horn) Corals, Pennsylvanian Period.
Camera: Nikon F5.
Lens: Micro-Nikkor 55mm f/3.5ai w/ Kenkos 12mm extension tube.
Film: Ilford Delta 400.
Filter: None.
These next fossils are known as Crinoid Stems. Crinoids, also known as “Sea Lillies”, were attached to anchors called a “Holdfast” (the stems and holdfast together called the “stalk”) These stems also known as the “Columnal” held the crown (aboral cup, arms, and pinnule) to the sea floor. Stems are usually the only thing left after decomposition, and it is a rarity to find an intact crinoid.
Crinoid Stems, Cambrian Period.
Camera: Nikon F5.
Lens: Micro-Nikkor 55mm f/3.5ai w/ Kenkos 12mm extension tube.
Film: Ilford Delta 400.
Filter: None.
thank you for checking out this blog, I will be studying more fossils from the group I found at Lake Oologah, stay tuned!
