‘Quanti canicula ille in fenestra’ on February 12, 2010 at 12: 07 am Claustrophobic inspector
The word fenestra is illustrated by a previous section of the Rule, No.LXXXII. p. 30.
The stapes, or stirrup, has its end of an oval shape, which fits a small hole called fenestra ovalis, in that part of the ear called the labyrinth, or innermost chamber of the ear.
This part has a round cavity called fenestra rotunda, which is covered with a thin elastic membrane, and looks into the tympanum.
This encloses an open space or "fenestra," so that the neck was not completely protected above.
It comes from the Latin de + fenestra, meaning window.
Verum quia non est expressum de quantitate fenestrarum, ordino, quod maior fenestra duplicata in longitudine sex pedes habeat, spacium sive banca inter cancellos unius pedis et palmi, cancelli duplices ferrei et quadratis virgis ita stricti, ut ne ovum galline possit transmitti.
"In ipsa uero ecclesia. in aliqquo loco intermedio inter sorores et exteriores aptetur aliqua fenestra ferrea competentis magnitudinis. in qua fiant sermones: et in aliquo loco apto due fenestre paruule ferrate ad confessiones audiendas."
I should have mentioned the temporal fenestra thing, but I wrote it late last night :P
It now seems that nearly all of the characters proposed initially to distinguish Tupuxuara from other pterodactyloid pterosaurs are problematic in not being unique to the genus, but in fact Tupuxuara is clearly diagnosable, being unique in having a sort of deep premaxillary crest in which the dorsal margin extends subparallel to the dorsal margin of the nasoantorbital fenestra (Martill & Naish 2006, p. 931).
