Pholadomya konincki
Pholadomya konincki
Summary
Pholadomya konincki was an infaunal clam that probably lived deeply buried in soft marine sediment. Like other pholadomyids, it was most likely a suspension feeder, using siphons to maintain contact with the water above while the rest of the animal remained protected within the seabed.
A deep-burrowing lifestyle would have reduced exposure to many surface predators and physical disturbance. Its ecology is inferred from the broader pholadomyid body plan because the fossils preserve the shell or moulds rather than the soft siphons and feeding organs.
Quick Identification
Look for: an inflated, inequilateral pholadomyid shell or mould with a subtrigonal-to-ovate form, prominent close umbones and preserved shell sculpture; complete outline and ornament are needed for a confident species-level identification.
Diagnostic Features
- Shell is inflated and inequilateral, with a subtrigonal to ovate overall outline.
- Umbones are prominent, close together and stand above the dorsal margin.
- Anterior end is comparatively short while the posterior part is more produced.
- Shell is relatively thin and may preserve concentric and radial surface sculpture where not decalcified.
- Species-level identification requires the combined shell proportions and ornament; feature-poor internal moulds are not diagnostic.
