Hello!
I have a question about Shergottite ejection age, I have read in many articles, like:
http://www.imca.cc/mars/martian-meteorites.htm
and
http://www.lpi.usra.edu/meetings/lpsc2011/pdf/2371.pdf

seems all the shergottite were ejected by the same event about 1.1 +- 0.1My ago.

But these articles talk about 0.7 +- 0.3 My

Any idea?

Thanks
Francesco!
