Late Triassic Mystery Fossil #4

This is an interesting specimen with an interesting history.....and proof that, to be cliche, one person's junk is another person's treasure (especially if they don't know what they are looking at). Unfortunately that is only half the story, the rest is highly frustrating. Views are lateral and proximal. Scale bar is 1 cm.


  1. I know but won't tell. I'll let someone else chime in, but you have to tell us the frustrating part.

  2. That's easy!
    It is clearly the proximal end of a silesaurid femur. The triangular shape in prox view and the lack of medial extension despite the little dinosaur like lip at the distal end of the articular head are pretty distinctive.
    I know - I'm showing off now.
