And some fossils.
I found an ammonite in the rocks but it isn't very good.
Also purchased this :

A shark vertebra from Otodus obliquus, about 55 million years old.
You can see where the neural arch connected as well as lots of tiny blood vessels.
I have smaller ones, but they are rarish because they are light and made of cartilage not bone, so don't preserve so easily, usually we only find shark's teeth, which are super hard and replaced all the life of the shark so are very common fossils
It's quite a large one and goes with lots of large teeth I have of this species.

And here is a nautiloid, Cymatoceras sakelavus , 112 million years old from Madagascar.
Polished to show the chambers.

And the venter showing a patch of white that is the original shell material (the majority has been replaced with agate) , not bad for this age.
The little hole is the entrance to the siphuncle a tube that connects the chambers and allows changes to the pressure of stored gas, allowing the animal to rise and fall in the ocean, a similar technique we use in submarines.

We visited a new restaurant
View attachment 198167
We were given menus by the waiter, an interesting and unusually varied selection at reasonable prices.

We ordered drinks and the the owner came out and said :
"Would you like to order food ?"
And before we could reply he chuckled and said :
"Well, you can't! The kitchen's closed".
And chuckling , he wandered off.
Was his name Basil by any chance?
