 Beskrivelse:   af  Benjamin Ramassamy 
Fossil remains of Odontoceti constitute a rare finding in the claypit. Their smallest representatives are only recognized from isolated elements such as earbones, teeth and vertebra remains.
In this context, the discovery of a new perioticum belonging to a small odontocete from the Gram claypit constitutes a unique finding. Interestingly, it is very similar to the morphology of other periotica found in the claypit, suggesting that they belonged to the same type of animal. Preliminary observations indicate those earbones to be very similar to Kentriodon hoepfneri, a Kentriodontidae from the formation of Gross Pampau in Germany, close in age to the Gram Formation. However, they differ from the latter in having a significant nudge in the posterior process of the periotic, a significantly less sigmoid shape of the periotic body and a blunter anterior process.

The discovery of this isolated periotic bone provides new information considering the identification of this small odontocete type and will provide new information concerning the ecology of this animal.

I recommend this fossil to the Danekræ comity for the rarity and high taxonomic value of whales earbones, and its exhibition value.
