I found this specimen in the summer of 2006. Technically, it's a partial crown, but in light of the
absence of any cup plates, I put it in this 'OTHER PARTS' section.



From the side, looking 'up' at this crinoid, you can see the 'wedge missing', 'half moon-ish' appearance
of the cross-section of the brachials (labeling to follow). 









Next are a couple side view shots.



Without any cup plates, it may not be possible to identify this crinoid, but if it were identified at some
point, it could help with understanding the Pinkerton Trail crinoids.



A look from 'above' the crinoid with this next set of photos reveals the characteristic look of the
brachial plates. Again, I will add some labeling here (and possibly a closer-up view) to help point out
this particular feature.





These last two images are just thrown in so you can see how the crinoid's arms continue throughout
the piece of matrix. Their general 'skinnier' appearance leads me to conclude that the brachial sections
nearer to this end of the piece of rock appear to be further toward the distal ends of their respective
rays on this specimen.



These segments are all brachial, yet there are more than five. Therefore, (barring the unlikely possibility
that there are more than one crinoid specimen lying side-by-side here together), we know that this is at
least somewhere above the second axillary brachial plate (IBr2ax).

Based on that, my interpretation is that the 'lower-most' axillary plates which we can actually see on
this specimen in the other images must be at least the third or fourth (IBr3ax or IBr4ax).
Thus, we can see either the fourth or fifth brachitaxis of this specimen, making it [part of] the longest
crinoid I've ever found.
