wellwellwell Posted April 9, 2019 Share Posted April 9, 2019 Found a complete version today, that looks very similar to a split object, found last week. It doesn't look like other worn bulla bones I have found in the same area, but at least the split piece has a distinct radiating grain, so I'm guessing it is not one of last nights leftover beans. Any suggestions would be appreciated, thanks. Link to comment Share on other sites More sharing options...

Rowboater Posted April 9, 2019 Share Posted April 9, 2019 Tilly bones (hyperostosis of fins and bones) come in several shapes and sizes. The elongated ones (often with ridges and enamel) as you and shellseeker show, and also more globular ones with the radiating lines often visible, even unbroken. Evidently the calcium regulating hormones were late to evolution, or needed fine tuning. Link to comment Share on other sites More sharing options...
