Finds from the Campanian Stage of the Urals

[Hyaena]

Hello again, dear forum users. At this point in time, we began to study a point with a Cretaceous (we believe that this is Campanian based on the fauna of shark teeth and lithology) fauna. These are mainly shark teeth and fragments of cartilaginous fish.
But there are also such mysteries. The main version is that this is either a fragment of coral or fragments of sea urchin needles. Particularly interesting is the strange formation on one of them, as if something had attached itself and was about to grow - a brachiopod?
The third question is about the tooth of synechodus, is it a tooth of synechodus lerichei? I'm right?
Best regards, Anton.

Pretty little things you will need an expert to give specific id on your shark tooth.

Hello dear forum visitors. We need your help again. With your permission, I will continue the topic, a find from the same pit. On our next trip we found such a curious tooth. There is an assumption that this is a tooth of a young Cretoxyrhina denticulata subadult.

I still know that adults don't have side toothbrushes

But he looks very thin and thin. Tell me please. Ural, city of Kamensk-Uralsky, sediments - Campanian. The size is exactly 2 centimeters
