Actually older than the Jurassic - similar plants areknown fromthe (old)CarboniferousPeriod.

You probably know this but you didn't say - for the benefit of ohers who might be curious these are the spore-producing fruiting bodies (fertile stems or strobili) of what is probably the Common Horsetail (Equisetum arvense), a primitive plant of worldwide distribution across the Northern Hemisphere.Such plantsbeen called "living fossils," as they are little changed from the earlier forms. Interesting to see photos ofthese structures, which are not often depicted. For an example of an extinct plant from thatearalier time period see the following thread:

Thank you for the information. I have some knowledge of the Natural History of Plants but not deep enough.

Somewhere in my catalogues there is a picture of a saprophyte, also without clorofyll. I'll find it
