Vaatindrukken op donderkeilen
Grondboor & Hamer , Volume 39 - Issue 2 p. 34- 47
Little is known about the belemnite animal. Therefore, a study was undertaken of the vascular imprints in Upper Cretaceous belemnites. Literature studies and observations of the author suggest that these may be imprints of bloodvessels. A review is presented of belemnite reconstructions. The rostrum was porous, and occupied a greater part of the shell than was currently assumed.
