(scleral ossicles), or often a combination of both, that comes together to form a ring. The arrangement, size, shape, and number of ossicles vary by group...

synapomorphies support this hypothesis, such as the presence of: sclerotic ossicles, paired pectoral fins, a dermal skeleton with three layers (a basal...

the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear, and thence to the oval window in the fluid-filled...

The orbits were very large and had a thick sclerotic ring formed from unusual spoon-shaped sclerotic ossicles. This indicates that it was likely a diurnal...

occupied much of the hind part of the skull. The sclerotic rings inside the eye were formed by eleven ossicles (small bones), similar to the amount in other...

misnomer: much of the clinical course is characterized by lucent rather than sclerotic bony changes, so the disease is also known as otospongiosis. The word...

thought to be related to the modern arowana, although the presence of a sclerotic ossicle in their specimens suggests that they were a deep-water fish unlike...

composed of three types of bone: cranial bones, facial bones, and ear ossicles. Two parts are more prominent: the cranium (pl.: craniums or crania) and...

species, P. solvayi, the sclerotic ring is only partially preserved, consisting of five scleral ossicles in each ring. Similar sclerotic rings are seen in several...

skull, the right orbit contains a nearly complete sclerotic ring which is composed of overlapping ossicles. The gracile hand of this specimen, which has particularly...

loss in OI may or may not be associated with visible deformities of the ossicles and inner ear. Hearing loss frequently begins during the second, third...

includes rarely preserved elements such as gastralia (abdominal ribs) and a sclerotic ring (a bony ring inside the eye). A larger, but poorly preserved specimen...

collagen. Mechanically, bones also have a special role in hearing. The ossicles are three small bones in the middle ear which are involved in sound transduction...

eye occupies a considerable amount of the skull and is surrounded by a sclerotic eye-ring, a ring of tiny bones. This characteristic is also seen in their...

large but the sclerotic rings to support the eyeball are not ossified. Some specimens preserve dozens of tiny round dermal bones or ossicles that were embedded...

Plioplatecarpus from the Campanian Bearpaw Shale (Alberta, Canada) preserved with a sclerotic ring is published by Holmes (2024), who interprets Plioplatecarpus as...

elements constituting the sclerotic rings varies between species : 12 ossicles in C. duelferi; 13 ossicles in C. buchseri; 14 ossicles in C. nichollsi; and...

with one ossicle per vertebra beginning with the first dorsal vertebra and continuing into the anterior caudal series, and fusion of the ossicles and neural...

crocodilians, the eye of Terrestrisuchus was supported by a ring of bony ossicles, the sclerotic ring. The body was relatively short and shallow, and the spine...
