Numbers below branches indicate absolute Bremer indices. (c) Schematic drawing of composition of the lower temporal region as observed in most lizards, depicting the independent development (connected by the arrow) of a complete LTB formed by the jugal (blue) in P. sternbergi and T. zhengi. ...
Uniquely among chondrichthyans, however, it demonstrates osteichthyan-like resorptive shedding of scale odontodes (dermal teeth) and an absence of odontogenic tissues in its spines. Our results identify independent acquisition of these conditions in the chondrichthyan stem group, adding Fanjing...
Hinge teeth inserted obliquely. Dorsal valve: hinge plate posteriorly forming a massive, characteristically shaped compact cardina- lium, involving median septum before dividing and forming closely parallel, long crura; the crura extend beyond midvalve, bending strongly towards the ventral valve, and ...
Whilst fluorosis may not be a direct cause of death, potential secondary causes of death, such as untreated infection from damaged teeth or bones caused by fluorosis, remain unknown and of concern. Further research into the prevalence of dental fluorosis in Malawi, particularly in the Southern ...
The dorsal and part of the right as well as little of the left lateral surfaces of the skull have been prepared (Figs. 4–6). Some ad- ditional skull elements and several teeth, which have detached from the major part of the skull, are spread over the slab and have been partially ...
The field work so far has resulted in the discovery of great numbers of vertebrate remains. These include marine reptiles such as plesiosaurs, mosasaurids, and turtles, as well as crocodiles, dinosaurs, and a variety of bony fish and chondrichthyan remains, especially teeth (AbdelGawad et ...
As shown in Figure 1F, the aspirated cayenne may be in tiny fragments after chewing by teeth or in one big segment with tiny fragments (Figure 3C). It can also be dispersed as two relatively big segments lodged in two bronchial lumens (Figure 3F). Flexible bronchoscopy Flexible bronchoscopy ...

Abnormalities involving heart, kidney, nails, teeth, hearing, and brain were not observed in any affected member. Heterozygous carrier individuals had no abnormality, and were phenotypically and clinically indistinguishable from other normal individuals. WES and sanger sequencing To search for disease ...
and elsewhere they are mostly represented by teeth and jaws, not foot skeletons. Fully articulated Cretaceous mammals are best known from the Yixian Formation in China34,35,36and incomplete foot skeletal remains have also been found in Mongolia37,38,39. Thus, the potential to match Cretaceous fo...
