23 presacral ( neck and back ) vertebrae are preserved in the holotype, although several may be missing because the typical number of presacral vertebrae in early synapsids is 27.
22.
The presacral fascia is limited postero-inferiorly, as it fuses with the mesorectal fascia, lying above the levator ani muscle, at the level of the anorectal junction.
23.
Ten of the standard 23 presacral vertebrae are missing, as well as the last several caudals of the tail-tip . confuciusornithines ( Chiappe et al . 1999 ).
24.
As the nervous system remains undamaged, individuals with meningocele are unlikely to suffer long-term health problems, although cases of sacrococcyx and of the presacral space, and Currarino syndrome.
25.
In nearly all other crurotarsans, there is one row of osteoderms per vertebra . " T . coccinarum " has around 20 rows of presacral osteoderms and about 26 presacral vertebrae.

The posterior and lateral cervix drains along the uterine arteries to the internal iliac lymph nodes and ultimately the paraaortic lymph nodes, and the posterior section of the cervix drains to the obturator and presacral lymph nodes.
28.
The Currarino triad ( OMIM 176450 ), due to an autosomal dominant mutation in the MNX1 gene, consists of a presacral mass ( usually a mature teratoma or anterior meningocele ), anorectal malformation and sacral dysgenesis.
29.
The vertebral column consists of nine presacral vertebrae, a single sacral vertebra, and a free phalangeal formula 2-2-3-4-3, with its fourth digit being the longest at 27 mm.
30.
However, it was established this was not the case, as there were significant anatomical differences between the two genera, including different presacral vertebral counts and the form of the gastralia, that could distinguish between the two taxa.
