Dear Matthew and colleagues,

I share your opinion that otoliths are particulary unstable.

Here is a link to a paper presented in last Fish research working group in Alghero. It is a about a 15th-16th c burial pit where 116 whole haddocks still with their skin that have been burried. In supplementary material in the end of the document the table presents a sample with the counts of skeletal parts. MNE for otoliths is 12 whereas basioccipital =35 pterotic=32 supraoccipital=30. Otoloiths could only have dissolved as the pit had been bulk sampled and sieved to 1mm mesh. So that means that only 1/3rd of the sturdy otoliths of this medium sized Gadidae (average total length based on 90 individuals of TL=49cm ) have survived the short burial period within an urban context where preservation is good !

This paper will not be published in conference proceedings so if anyone has suggestions on a journal where it would be suitable to publish please let me know off-list.

Best regards,

Tarek

Dear colleagues

Ngā Mihi o te Tau Hou / Happy New Year

Do any of you know anything about the taphonomy of otoliths? I have observed that they survive very well in some sites and not at all in others, but I can’t see any reason for this.

If anyone can shine any light on this topic or point me to any references I would be grateful (searches on Google Scholar and ResearchGate didn’t help)

Mat
