Samples Saved:
otoliths Furtner Analysis:
stomach content i.d.
l Comments: right maxilla from young (neonate?) harbor seal pup. No teeth present. As no other decomposed seals of this size hav
- been recovered recently, and bone does not match recently recovered bones, this appears to be a young seal that was not recovered until completely decomposed. If seal was quite young it is likely that it would sink and decompose rapidly.'"
(Revised report)
Recovered bone fit missing piece of skull of this animal, Seal appeared to be average condition young-of-the-year seal pup.
Although this seal was young, it was not as young as previously expected. Advanced decomposition limits analysis, however, no significant parasites or disease were noted.
