SMNK-PAL 10,000a, CT sections through the right radius and the penultimate phalanx of the right digit II. A. CT section 1 according to Fig. 8A. A’. line drawing of CT section 1; B. CT section 2 according to Fig. 8A. B’. line drawing of CT section 2; Note that the “furrows” are generated by compaction (red arrows) that caused linear cracks along the long axes of the bones with the medullar cavity still being mostly hollow. The bones must have been fixed in the matrix prior to compaction, because the bone parts did not separate from each other. The radius might have been subject to an internal pressure that caused a separation of the upper and lower bone elements (blue arrows).
