Fulgurite variation or a Bathichnus paramoudrae? |
| « Previous | Next » |
A: Bathichnus paramoudrae in lower Maastrichtian flintless chalk, 30-35 m below the marl band at Hemmoor. The subvertical shaft makes a sudden bend near the top. A side branch at (a) has been flattened by compaction while another at (b) is uncrushed. This specimen was extracted and chosen as Holotype, MMH 13058. B: enlargement of part of A, showing the fragmentation of the glauconite tube. Width of tube: 1 cm. C: upper termination of a burrow at Kronsmoor, apparently truncated by erosion (a). The burrow is represented by a thin pyrite tube, and is surrounded by an auriole of dark grey, pyrite-stained chalk. Two pyrite concretions lie close to the burrow (b,b) >(")< Article and unique photos about Paramoudras, Flint Circles and Flint Backbones on Beeston Bump Beach can be found at >{}}@> http://www.geulogy.com/norfolk/beestonbump/introdis-beestonbump.html ~~%~~!~~~/~~ Photo and text credit Bromley, Schulz & Peake 1975
