An examination of the tissue showed that the proximal bony segment of each ray arises from a suspensorium
with a cartilaginous base and consists of two concaved discs of acellular bone, surrounding a medullary cavity.
distinct, ringshaped, loosely encircling aedeagus.
Another example concerns the attachment of the Aw on the suspensorium
and/or opercular series (134: 0 [right arrow] 1).
Vertebral numbers and structure of the gonopodial suspensorium
were determined from cleared and alizarin-stained specimens.
PRELIMINARY NOTICE OF A THIRD PALEONISCOID (ACTINOPTERYGII: PALAEONISCIFORMES), WITH A VERTICAL SUSPENSORIUM
, FROM THE UPPER DEVONIAN (FAMENNIAN, IIf) CLEVELAND SHALE OF CUYAHOGA COUNTY, OHIO.
1995); the protractor pectoralis (PP), is a major protractor and stabilizer of the pectoral girdle; the adductor arcus palatini (AP), adducts the cheek elements (suspensorium
) causing compression of the buccal cavity.
. The hyomandibulosymplectic cartilage, consisting of cartilaginous precursors to the hyomandibular and symplectic, is visible at 5 DPH.
This clade is supported by a bootstrap value of 75% and by four unambiguous synapomorphies: presence of characteristic scaphium (69: 1 [right arrow] 2), intercalarium (72: 1 [right arrow] 2), tripus (76: 1 [right arrow] 2) and os suspensorium
(78: 1 [right arrow] 2).
: Comprising palatoquadrate arch, ectopterygoid, mesopterygoid, ectopterygoid, symplectic, hyomandibula and preopercle (Fig 9).
