From: Wretch Fossil on 26 Mar 2010 01:19 Most meteorites contain fossil bone remains Reason 1: Most meteorites contain chondrules (note 1); Reason 2: Chondrules are surrounded by petrified remains of osteons (basic units of all compact bones) as shown in Figure 1 (note 2). Conclusion: Most meteorites contain fossil bone remains. (Bonus: Many iron meteorites also contain fossil bone remains, although they may not contain chondrules.) Figure 1: showing chondrules surrounded by petrified osteon remains. http://www.wretch.cc/album/show.php?i=lin440315&b=28&f=1176754883&p=55 Source of Figure 1 above: first photo in the Wikipedia article on chondrules at http://en.wikipedia.org/wiki/Chondrule Note 1: see second paragraph in the Wikipedia article at http://en.wikipedia.org/wiki/Chondrule Note 2: As meteorites have been highly compacted, many lacunae and canaliculi are missing from osteon remains, as lacunae and canaliculi are just spaces for cellsÂ’ homes and nutrient supply routes. |
