Fig. 3 in Differential preservation of the Upper Cretaceous ammonoid Anagaudryceras limatum with corrugated shell in central Hokkaido, Japan

Fig. 3. Categories of shell fragmentation patterns. A. Intact, NSM PM 17534. B. Phragmocones with distorted body chamber, with radial edges almost straight or paralleling growth lines, and located just adoral of last septum, NSM PM 17535. Note body chamber part retaining their original morphology. C. Phragmocones lacking body chambers, with edges almost straight or parallel to growth lines, and located just adoral of last septum, NSM PM 17536. D. Isolated body chamber parts, NSM PM 17537, lateral (D1 and D3) and ventral (D2) views. Note lower jaw (arrow) preserved near separated body chamber. All specimens belong to late Turonian (Late Cretaceous) lytoceratid ammonoid Anagaudryceras limatum (Yabe, 1903) from the Oyubari area in the central Hokkaido, Japan. Specimen B is from locality NSM PCL 4−24−1, and all the others are from NSM PCL 4−24−2. Triangles indicate position of last septum.
