Fig. 4. Comparison of taphonomic attributes between Anagaudryceras limatum (Yabe, 1903) and other planispiral ammonoids. A. Fragmentation patterns. Numbers around pie diagrams signify number of individuals in each category. B. Size−distribution patterns and mean shell diameters of specimens whose diameters can be measured. Categories: a, intact; b, phragmocones with distorted body chamber; c, phragmocones lacking body chambers; d, isolated body chamber parts; e, indeterminate.
