Recommended Posts

Hello all,

 

I found this fossil today at Portugal, Lisbon district, about 270 meters high.

 

Anyone knows what it is?

 

Thanks for your help.

 

Best regards

Another option is a gastropod.  I say that because it looks like it tapers to me and in some of the pictures I believe I see the columella on the inside.  It would be a big snail, that for sure!  Any idea on the age of the rock?

I agree this is a gastropod, i also see the columella.

The center part of a coiled gastropod is called the columella. You usually can’t see it except when a shell is broken open (as is the case here), although it also extends from the bottom of the shell in those forms with a siphonal canal. See the illustration below that I borrowed from the Geological Museum of Trinity College in Dublin website. The columella is circled in red.  I believe the specimen in question is a portion of a gastropod with the columella exposed in a couple of places.

Yes. It probably is. I did notice the likely spiral shape, but I couldn't find one at the time.

Campanile?

According to its size, that would fit.
