Soft fibrillar bone tissues were discovered within a brow horn of Triceratops horridus collected at the Hell Creek Formation in Montana. Soft material was present in pre- and post-decalcified bone. Horn material yielded numerous small sheets of bone matrix that had yet to turn into hard bone. This matrix possessed visible structures consistent with bone osteocytes. Some sheets of soft tissue had multiple layers of intact osteocyte tissues featuring elegant filipodial interconnections and secondary branching. Both oblate and stellate types of osteocytelike cells were present in sheets of soft tissues. SEM analysis yielded osteocyte cells featuring filipodial extensions of 18 to 20 microns in length. Filipodial extensions were delicate and showed no evidence of any permineralization or crystallization artifact and therefore were interpreted to be soft. This work is the first to report soft tissues from adult Triceratops horn in a Creation journal.
