Is this an anenome fossil?

Hello, my neighbour found this in her garden - is this some kind of anemone, if it is indeed a fossil?

We live in West Hertfordshire, UK, on the Chiltern hills.

Thanks

Hello, and a very warm welcome to TFF from Morocco. 

I guess you mean anemone? 

Or sea anemone? 

Anyway, no it isn't. I think it's just cochoidal fracturing of a flint nodule from the chalk. 

Keep looking, as some flint nodules do contain fossils, often sea urchins or sponges, for example.

Thanks for your welcome and quick reply to my question.

Although disappointed we'll keep looking - and we did discover this great site!

Many new members arrive here when they've found an intriguing rock (though the majority of times they turn out to be geological oddities and not fossils). There is a lot of fossil information stored in the older posts on this forum (over a million of them) :o and a little searching may turn up fossil locations near your area. Hunting for fossils can be a fun, informative (and highly addictive) hobby. If your interest is piqued, maybe you'll locate some places nearby where you can find some fossils and start building a collection.

 

Cheers.

Welcome to the forum! I think you do have a fossil there. The crystal lined cavities, central and branching, are probably the remains of a rather nice sponge. There are many types found in flints - I'll have a look at a few references tomorrow to try to narrow this one down. Sponges are often (usually!) difficult though and need microstructure and a specialist - overall shape tends not to be enough.  :)

 

(It's conchoidally fractured on the other side (first photo), with no fossil visible, as @Tidgy's Dad said.)

I'll be quite happy to be wrong. :BigSmile:

I agree with TqB, although I certainly can see why Tidgy's Dad focused on the conchoidal fractures.

In my thinking it's a very nice flint nodule. :)

I could be wrong, as well.

I messed up with the photo order in my first posting - the 'interesting' side should have been at the top. :DOH:
