2 unusual facts about Anatomical terms of location


Eugraphe

Most characteristic in the female genitalia is the ostium bursae, which has posterolateral extensions shaped like a bear's ears.

Spatial relation

In Anatomy it might be the case that a spatial relation is not fully applicable.


Cyphornis

It is only known with certainty from a single specimen, the rather abraded proximal part of a left tarsometatarsus which was found at Carmanah Point on Vancouver Island (Canada), where the Juan de Fuca Strait opens into the Pacific.

Elopteryx

Initially, Elopteryx was described from its holotype, a proximal left femur, specimen BMNH A1234.

Macrodontopteryx

An Early Oligocene (Stampian, MP21-23, about 32 Ma) distal radius from Hamstead, Isle of Wight (England) was also assigned to Macrodontopteryx.

Moorhen

For example, specimen QM F30696, a left distal tibiotarsus piece from the Oligo-Miocene boundary at Riversleigh, is similar to but than and differs in details from "G." disneyi.

Owlet-nightjar

A fossil proximal right tarsometatarsus (MNZ S42800) was found at the Manuherikia River in Otago, New Zealand.

Palaeochenoides

The first fossil assigned to it – a distal right femur piece – was found near the source of the Stono River in Charleston County, South Carolina (USA).

Palaeocursornis

The only known species, P. corneti, was described in 1984 based on a single bone (MTCO-P 1637) interpreted as the distal part of a left femur, found in Early Cretaceous (Berriasian rocks (dating to around 143 mya) from a mine at Cornet near Oradea in northwestern Romania.

Tridactylidae

They have several unusual features, for example, the posterior femora are greatly enlarged, being strongly adapted for leaping; in some species those hind femora actually are larger than the abdomen.

Turnstone

There exists a fossil bone, a distal piece of tarsometatarsus found in the Edson Beds of Sherman County, Kansas.

Tympanonesiotes

The only known specimen (USNM 16809), a distal right tarsometatarsus end, was found in the Cooper River near Drum Island at Charleston, South Carolina (USA).

Ventral nerve cord

It usually consists of cerebral ganglia anteriorly with the nerve cords running down the ventral ("belly", as opposed to back) plane of the organism.
