Rhaetian Lorraine Region

Rhaetian fossils from the Lorraine region.

Rhaetian Fish

 

Fish remains are abundant in the Rhaetian bonebeds from the Lorraine region. Teeth, scales and little pieces of jaw from different species have been recovered. Rhaetian fish are not my specialty so a large number of specimens remain undetermined in my collection. The scales are particularly difficult to identify. Even though some specimens will be presented without names, they remain "eye candy" and thus are worth illustrating.

 

 

Fossil fish remains

Sargodon tomicus Plieninger, 1847

 

These spoon-like teeth are common in the Rhaetian deposits. They stand out because of their unusual overall shape. They are the incisiform teeth of this species.

Sargodon tomicus Plieninger, 1847

These rounded teeth are found very often in the Rhaetian material. Sizes vary quite a bit. Usually teeth of this species are found without roots. They are the molariform teeth of Sargodon.

Gyrolepis albertii (Agassiz, 1835) 

 

These scales are abundant in the Rhaetian deposits. Quite a lot of them are broken, but pristine examples are also common.

Severnichthys acuminatus (Agassiz, 1839)

 

 

The pointed teeth of this species are common in Rhaetian outcrops. Some of them are beautifully preserved, as seen in the picture. Yet, in most cases the root is still missing. Most teeth are found this way.

Unidentified fish scale

 

 

 

This type of scale is in no way similar to any other scale retrieved from this outcrop. It is an interesting specimen.
