Leptaena rhomboidalis and Levenea lenticularis brachiopods from the Onondoga formation

Two more brachiopods that I found in a quarry near Syracuse this past May are this Leptaena rhomboidalis....

...and what I think is a Levenea lenticularis

Both specimens come from the Edgecliff member of the Onondoga Formation (Devonian, Eifelian stage) and were ID'ed using the paper "STRATIGRAPHY OF THE ONONDAGA LIMESTONE (DEVONIAN) IN CENTRAL NEW YORK By William A. Oliver, Jr (Bulletin of the Geological Society of America VOL. 66. PP. 621-662. JULY 1954)."
