About this file
The document is a printable trading card set titled "Life in Ancient Ohio Series 2" produced by the Ohio Geological Survey and Ohio Department of Natural Resources (ODNR), specifically the Ohio Rocks! Earth Science Education program. The set contains seven detailed trading cards featuring extinct species found as fossils in Ohio, including a sea scorpion (Megalograptus ohioensis), a rhombiferan (Anartiocystis foerstei), a trilobite (Eldredgeops milleri), a shark (Orthacanthus compressus), an amphibious tetrapod (Diploceraspis burkei), a conulariid (Paraconularia subulata), and a giant ground sloth (Megalonyx jeffersonii).
Each trading card provides comprehensive scientific information about the specific fossil species, including its age, habitat, size, unique abilities, pronunciation, and a thought-provoking question to engage learners. The cards are designed as an educational resource, featuring illustrations of each species in their probable prehistoric environments, with precise geological dating ranging from the Early Silurian period (approximately 440 million years ago) to the Late Pleistocene epoch (approximately 11,700 years ago). The trading cards are available for printing and can be accessed via a QR code and the website ohiodnr.gov/LIAO, with recommended printing instructions provided on the reverse side of the document.

Megalonyx jeffersonii was a large mammal related to extant tree-dwelling sloths. U.S.
President Thomas Jefferson named the fossil genus Megalonyx (“great claw”).
AGE OF OHIO FOSSILS:
Late Pleistocene, ~129–11.7 thousand years old
HABITAT: Woodlands
THINK: How might its large size have helped or harmed Megalonyx?
SIZE ABILITY

~10 feet long Could stand on hind legs
Megalonyx jeffersonii Extinct giant ground sloth meh-guh-LAH-niks jeff-ur-SO-nee-eye
Diploceraspis was an amphibian-like animal with a flat, boomerang-shaped skull and short, conical teeth. Its long tail moved side-to-side to propel it through the water.
AGE OF OHIO FOSSILS:
Pennsylvanian–Permian, ~305–290 million years old
HABITAT: Freshwater lakes and ponds
THINK: What function(s) might the shape of the skull have served?
SIZE ABILITY
geology.ohiodnr.gov
Skull up to ~6 inches wide
May have burrowed in mud
Diploceraspis burkei Extinct tetrapod dip-lo-suh-RASP-iss BURK-eye
Orthacanthus compressus Extinct shark or-thuh-KAN-thuss kom-PRESS-suss
SIZE ABILITY
Orthacanthus was an eel-shaped predatory shark with a long spine sweeping back from its head. Its pointy teeth each had two large cusps that formed a “V” shape.
AGE OF OHIO FOSSILS:
Pennsylvanian–Permian, ~305–290 million years old
HABITAT:
Freshwater to marine
THINK: What function(s) might the spine of Orthacanthus have served?
geology.ohiodnr.gov
Up to ~10 feet long
Survived in fresh- and saltwater
Eldredgeops milleri Extinct arthropod
EL-drej-ops MILL-ur-eye
SIZE ABILITY
Eldredgeops, a trilobite, had compound eyes with many separate lenses. The lenses were part of its exoskeleton and composed of the mineral calcite (CaCO3).
THINK: What modern-day animals have compound eyes?
geology.ohiodnr.gov
Up to 3–4 inches long
Molted its exoskeleton to grow
AGE OF OHIO FOSSILS:
Middle Devonian, ~385 million years old
HABITAT:
Marine
SIZE ABILITY
Anartiocystis, a rhombiferan (rahm-BIFF-uh-run), was a relative of sea stars and crinoids. It fed on plankton and organic matter floating in seawater.
AGE OF OHIO FOSSILS:
Early Silurian, ~440 million years old
HABITAT:
Shallow marine
THINK: Do you think Anartiocystis had predators? Why or why not?
geology.ohiodnr.gov
Main body <1 inch wide
Made a skeleton of crystal plates
Anartiocystis foerstei Extinct echinoderm an-ar-tee-o-SISS-tiss FUR-stay-eye
Megalograptus, a eurypterid, or “sea scorpion,” had an exoskeleton made of chitin. It had appendages for swimming and for detecting, grasping, and shredding prey.
AGE OF OHIO FOSSILS:
Late Ordovician, ~450 million years old
HABITAT:
Shallow marine
Up to ~30 inches long
Used body hairs as sensory organs
SIZE ABILITY

Megalograptus ohioensis Extinct arthropod meh-guh-lo-GRAP-tuss o-hi-o-EN(T)-siss
THINK: How are extant land scorpions like/unlike extinct sea scorpions?
Paraconularia subulata Extinct cnidarian pair-uh-kahn-u-LAY-ree-ah sub-u-LAY-tuh
SIZE ABILITY
Paraconularia, a conulariid, was likely a cnidarian—a relative of jellyfishes and corals. Some Paraconularia fossils occur in clusters with their bases closely spaced.
AGE OF OHIO FOSSILS:
Early Mississippian, ~355 million years old
HABITAT:
Marine
THINK: What parts of conulariids were most likely to become fossils?
geology.ohiodnr.gov
Up to several inches wide
Built a four-sided exoskeleton
