Although the Cretaceous period lasted from 145 to 66 million years ago, geologic units from the Berriasian to Albian stages and several terrestrial units of Albian to Maastricthian age are not chalky in terms of geologic composition. I remember that the Cretaceous at one time was divided into the Neocomian, Gallic, and Senonian epochs, so one day International Commission on Stratigraphy should divide the Cretaceous into the Neocomian, Gallic, and Senonian periods, since the Cretaceous lasted longer than either the Triassic or Jurassic. This is similar to the fact that American geologists divide the Carboniferous in North America into the Mississippian and Pennsylvanian due to Mississippian deposits being marine and Pennsylvanian deposits being formed from coal. -
These heteromorph ammonites were found in the middle East in a senonian outcrop. In a limestone but the fossils are made of flint and removed by acid. the pieces are 3-4 centimetres long and are three different individuals. Can you please help me ID them?

I went back from Touraine (about 200 km South from Paris) and i found those two sponges which i think might be siphoniae multioculatae, but i'm not expert at all. They're quite flat. Each square is half a centimeter. What do you think ? 1) 2)

Hi, I show you two more pieces that might only be concretions but i have doubts and i would like to know if you agree with that or no. 1) about 8 cm on 6 cm.

Another piece i found in the Turonian- Senonian (-91 to -83 my) of Touraine is that brachiopod. It is about 3,5cm wide and hight. It is probably a Cyclothiris (or Rynchonella) vespertilio, but as i know little about brachios, i need your opinion :

Hi everybody, i found some items in the department of Loir et Cher, region Touraine, at about 200 km at the south of Paris, France. The place where i found it covers from the Turonian to the Senonian (-91 to -83 my). Most of the sponges you find there are siphoniae or chenendoporae, but you can also find jereae, phymatellae or pachysalaxe. I think this one might be a chenendopora. It is in black silex and is about 7 cm wide and 6 hight.
