While this is an extremely interesting and aesthetic large fossil slab showing a variety of prehistoric Ordovician marine life fossils, it includes two amazingly well preserved Conulariida fossils that exhibit ULTRA RARE SOFT PART preservation so detailed that this piece possesses an enormous scientific value, as well. Conularia fossils have been known to exist for over 150 years and still, scientists do not know what they are! Many fossils are just impressions of these alien creatures but THIS specimen shows bizarre and rare detail that most other specimens lack. This slab would be an ideal addition to any major public museum wishing to exhibit an extraordinarily well-preserved example of this rare creature. The slab would also make a monumental display piece demonstrating various forms of Ordovician sea life from well over 400 million years ago. This specimen is 100% AUTHENTIC WITH NO FABRICATION. The detail of the fossils seen are of the type only found for genuine specimens. This is an both, a SCIENTIFICALLY IMPORTANT AND VISUALLY STUNNING exhibition fossil.
This remarkable fossil showcases a NATURAL mass death association of a variety of marine creatures. There are 2 Conulariida fossils, a spectacular and large 6 inch Selenopeltis trilobite, another negative impression of another Selenopeltis trilobite but with most of the positive fossil spines attached to the impression, numerous unusually large onnia trilobites and numerous rare spiny-tailed Mucronaspis sp. trilobites, a Dalmanitid-type trilobite. This is a 100% NATURAL ASSOCIATION OF ALL FOSSILS SHOWN ON THIS SLAB. NONE HAVE BEEN ARTIFICIALLY ATTACHED as is common with many kinds of group fossils, especially from Morocco. The Selenopeltis trilobite is a spectacular specimen but the real celebrity of this piece are the two Conulariida fossils, namely, the giant and bizarrely preserved FOOT LONG CONULARIA specimen! This conularia fossil shows rarely seen large pore anatomy and a complete, full inflation coming off the rock. The distinct longitudinal segments are dramatically visible and the entire creature with both ends, is preserved on the rock. Every conularia fossil we have seen from Morocco is nothing more than a faint, painted impression on the rock lacking any detail like this. These fossils on this slab exceed anatomical features and detail we have encountered in any North African specimen. Quite frankly, the anatomy of this fossil is so strange, it would be hard to determine just what creature it is if it were not for the overall prominent 4 longitudinal segments that are known to Conulariids as well as the overall shape and the formation and period of this occurrence. In addition, they are enormous examples of this strange extinct marine animal. From a scientific perspective, this is a true PRIZE specimen that may shed further light on many unanswered questions of just what the conulariida are. Seldom are scientifically important fossils also impressive to the public but this specimen fills the need on both accounts! This is the most impressive and fine example of its kind we have ever come across.
Conulariida are a mystery to science to this day. The occurrence of them in the fossil record is not necessarily rare but SOFT TISSUE PRESERVATION as is shown here IS BEYOND RARE. There have been very few instances of soft body tissue preserved compared to the segmented inner structures that are typically found in fossils. These two rare examples shown above exhibit what appear to be a collection of varied size pore openings across the body. The full edge detail is also quite prominent showing what the entire outer body profile looked like when alive. The deep furrow of the inner, longitudinal segments are obvious and dramatic. Being able to see what the outer body structure looked like on these enigmas of science as can be seen in this fossil, just may answer or confirm some of the questions that have baffled scientists for over a century and a half! Conulariids first appeared abruptly in the fossil record in the Middle Cambrian Period and exist into the Triassic. They may represent an entirely extinct phylum but so little is really known about them. The fossils they are found in represent the bottom of off-shore marine environments. Conularia are believed to have been filter feeders attached to substrate on the ocean floor but very few soft tissue fossils exist with most showing the internal calcite segmented structures. A noticeable feature is their longitudinal four-fold segmented body structure.
