Fossul Posted April 9, 2023 Share Posted April 9, 2023 Hi all, Would be really grateful if anybody could help identify this fossil. The piece was found in South East England. Unfortunately the provenance is a bit murky but I believe it was claimed to have been found on a beach. Attached a series of (compressed sized) pictures showing the specimen from several angles with international scale Link to comment Share on other sites More sharing options...
TqB Posted April 9, 2023 Share Posted April 9, 2023 Welcome to the forum. It looks like a piece of calcareous tufa, enclosing various twigs and plant fragments. It's often post-Ice Age, formed in limestone caves and fissures, so relatively recent. 2 1 Tarquin Link to comment Share on other sites More sharing options...

It's just twigs and/or reeds really - these circular sections containing a separate hollow ring are typical of a lot of the tufa I've seen in my own area.

I've seen tufa in streams, washed out of caves and fissures, where the stems are in various stages of calcification and decay. Sometimes they're more obvious than here but it's a distinctive texture, as is the calcite layering.
