Agatized
Camarocrinus Crinoid Bulb Fossil Oddity from Oklahoma |
|
Name: Camarocrinus
ulrichi
Age: Devonian
Size: The bulb is 3 5/8 in diameter, an 2 ¾” in length.
Fossil Location: Haragan Formation, Arbuckle Mountains, Ada, Ollahoma
Comments: A true fossil oddity, not unlike petrified wood. The
interior of the crinoid bulb filled in with minerals and became
agatized over the eons. These crinoids were attached to the bottom
of the sea and this was the flotation bulb.

Early
Soft-Bodied Ediacaran Porpita porpita Fossils from Australia
|
|
Name:
Porpita porpita
Phylum: Cnidaria Class: Hydroza
Age: Ediacaran Period - 580 Million Years Old
Size: The fossils are ½” to 5/8” in diameter
Fossil Location: Ranford Formation, Kunnunarra, West Australia
Comments: This putative Cnidarian comes from the Ranford formation
of Australia. It dates to the Ediacaran Period, nearly 40 million
years before the Cambrian Explosion. Like most Ediacaran fossils,
whether they are truly fossils or pseudofossils is debated
and equivocal. For these, some argue they are cnidarian medusaforms
and some that they are non-biogenically produced artifacts.
They
bear a striking resemblance to the extant pelagic cnidarian
porpita (or blue button). The Ediacaran biota include the
oldest definite multicellular organisms with tissues, and
the most
common types resemble segmented worms, fronds, disks, or
immobile bags. They bear little resemblance to modern lifeforms,
and
their relationship even with the later life forms of the
Cambrian explosion is difficult to interpret. The evolutionary
divergence
of cnidarian and bilaterian lineages from their remote metazoan
ancestor occurred at an unknown depth in time before the
Cambrian, since crown group representatives of each are found
in Lower
Cambrian fossil assemblages. The multicellular cnidarians
evolved early on earth and despite their primitive nature
have endured
for hundreds of million of years since. It remains uncertain
whether bilaterians evolved from early cnidarians or from
the hypothesized triploblastic ancestors of cnidarians. These
fossils
are very rare and have been legally collected.

Plumulites Annelid Feathery Worm Fossil
|
|
Name:
Plumulites
Phylum Annelida,
Order Turrilepadomorpha, Family Plumulititidae
Age: Ordovician (Machaeridian)
Size: The Plumulites is a large 1 7/8” in length
Fossil Location: Lower Ktaova, Mecissi, Morocco
Plumulites was a slug like Metazoan, or, armored worm. The
armoured annelid worm is the relative of the modern-day earthworm,
leech and bristleworm. They have only recently been quarried
and brought to the fossil market place. Generally, the preservation
of the fossils is sketchy and poor, as they were soft-bodied.
This specimen is well preserved presenting a bright rust/orange
color displaying excellent detail of the feathery appendages.
The spinal cord is clearly evident.
