Stukje kaak

[mars33]

Een kennis van mij heeft op het Noordzeestrand vlak bij de Oosterscheldedam deze onderkaak gevonden en was benieuwd waar het van is. Ik dacht eerst aan een hertachtige, en dan een ree, maar volgens mij zijn de kiezen daarvoor iets te hoogkronig en de onderkaak ook wat te hoog, dus een geit/schaap leek me daarom logischer. Your thoughts?

Looks like a bison from first glance due to the teeth.

Voor rundachtige, dus ook bison, te klein. Voor schaap of geit te groot. Probeer te determineren op een hertachtige. Doorzoek het forum eens, er zijn meerdere topics over geschreven.

precies de juiste grootte voor een schaap of geit. Eveneens hoogkronige kiezen dus zeker geen hert.
Rechter onderkaak fragment.

It could be a juvenile Bison, like my specimen in the picture. But I also agree it could be a deer partial jaw.

@ Thomas:
You can defenitely trust The Stone on this kind of fossils, he knows them very well. The difference between deer and bison/cow/goat/sheep is whether the molar is 'high' or 'low' compared to the jaw. That's caused by their diet. Deer eat a lot of soft leave and soft grass material, whereas the other mentioned animals eat much, much tougher grass, which erodes the molars much faster. Therefore, the molars have to be comparitively higher than deer's.

I fully agree with The Stone on this specimen: sheep/goat. The size is correct and the molars are 'high'.

I never said the stone was wrong. But now I have learnt something new about the molars on fossil teeth.

Bedankt voor de determinatie. Ik neem aan dat er over de ouderdom niet veel valt te zeggen? Middeleeuws oid?
