...DANITA S. BRANDT; JAYME CSONKA; MEGAN HOLYCROSS; VICTORIA MCCOY; MEGAN SEITZ Abstract Arthrophycus is an iconic ichnogenus known from lower Paleozoic clastic strata worldwide, yet its origin remains controversial. A medial groove imparts a bilobed symmetry in some forms, implicating arthropods...

The biologic affinities and habitat of Arthrophycus are in question, but the Lower Silurian eurypterids and fish probably inhabitated fresh water. The combined lithologic and faunal evidence supports...

The presence of Arthrophycus in the Thorold of the Niagara Gorge and its absence in the “3 feet of ‘white’ sandstone” topping the red Medina in the Genesee Gorge are noted by Professor Chadwick. Arthrophycus does occur at this horizon in the Genesee Gorge. It is probably not plentiful...
