2 could be due to taphonomic processes or natural range of variation for this species. The sharp ridges and the size of the specimen here support this species assignment. In fact, the sharp ridges are very similar in shape and only slightly higher in the new specimens presented here. The endocarp wall is also very similar in all aspects. The size of the specimens presented here brackets the values of the specimen from Rivecourt. Therefore, we have sufficient justification to attribute these specimens to
