Massive Trilobite Mortality Plaque

Massive Trilobite Mortality Plaque
Asasphellus sp.
Lower Ordovician
Zagora, Morocco
Exceptionally well preserved, impeccably prepared mass mortality trilobite plaques such as this example are rare. Such assemblages may have formed as a result of mating or molting activity or as the direct result of a prolific trilobite-filled marine estuary drying up due to a naturally-occurring event, such as an earthquake or undersea volcanic eruption. The present presentation boasts almost countless superb asaphid specimens within their original, irregularly shaped matrix, prepared in handsome relief. Measuring 47 x 38 1/2in
