Shellseeker Posted February 8, 2022 Share Posted February 8, 2022 When I first picked up this fossil, I noted lines that reminded me of fossilized ivory, but not quite. A friend polishes fossils and rocks....I asked that he polish one end... Sometimes it looks like bone.... And sometimes it looks like fossilized wood, and occassionally, I seem to see Schreger lines. All suggestions appreciated. 2 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

Thanks, you are likely correct... As I found it, I attempted to ID Mammoth, Mastodon, or Gomph based on Schreger lines, and different views seems to show different angles,, and in photo # 4, I stared for a long time at the longitudinal straight lines in lower left... The Schreger lines seem to be 90 degrees. @darrow The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
abyssunder Posted February 8, 2022 Share Posted February 8, 2022 There are Schreger lines, so it's a proboscidean tusk fragment. Nice find!

darrow Posted February 10, 2022 Share Posted February 10, 2022 Schreger line angles vary considerably across the diameter of a tusk. Small areas taken alone can be misleading. This piece is Mammoth I believe. 2 Link to comment Share on other sites More sharing options...
