The next osteoderm is additionally triangular however, wider as compared to first osteoderm
5.8.step one Prior cervical paramedian osteoderms
The original about three paramedian rows of the right side is maintained inside PEFO 34561, and some rows try kept into the PEFO 42442/UWBM 116869 (Figure 12h). The initial osteoderm is roughly triangular within the dorsolateral take a look at that have straight medial and you can posterior entation is actually weakly incised, and there’s zero anterior pub. Instead, for the prior ventral body there is certainly a great scalloped, rugose facial skin to own articulation to your rear margin of one’s head. So it osteoderm is much like the initial within the morphology except it lacks the fresh ventral articular skin and you may rather enjoys an effective weak anterior bar along the narrow prior margin. The 3rd osteoderm try square (mediolateral depth:anteroposterior size proportion of dos.0), with a beneficial dorsal ornamentation from short pits. This osteoderm was curved near its lateral border, and there is a pronounced anterior club which have good triangular anterior projection at the part out-of arching. The ventral epidermis of one’s plate are smooth. Inside the dorsal examine, the fresh new medial margin try straight, while brand new horizontal margin try carefully circular and you may does not have a keen articular body for a horizontal osteoderm.
