#カルカロドントサウルス科

[mesozoicmarket]

A partial dinosaur tooth of an indeterminate theropod from an unknown locale. It was labeled as possibly from the Yixian Formation thus potentially Yutyrannus huali. However, the odd orange preservation does not match that of this deposit according to those familiar with the formation; I'm also not sure if that darkened spot was caused by fire damage. The distal serration density of 20-21/5mm seems a bit high for Yutyrannus based on what's described from Sinotyrannus which is around 15-16/5mm, and it's unclear whether the tooth has a mesial carinae. There is a possibility that it belongs to the Cretaceous carcharodontosaurian tooth taxon, Prodeinodon. A very unusual tooth, but unfortunately the dubious provenance makes identification extremely difficult if not impossible.

A dinosaur tooth of an indeterminate carcharodontosaurid, possibly Eocarcharia dinops from the Elrhaz Formation in Gadoufaoua, Niger. The size and basal morphology of the tooth would suggest a large carcharodontosaurid similar to that of Acrocanthosaurus than what is currently known from the dentition of Eocarcharia. However, there is little known about the full dentition of this species, and most phylogenetic placements classify it as a basal or early diverging carcharodontosaurid.

A very worn dinosaur tooth of an indeterminate theropod, possibly Neovenator salerii from the Wessex Formation in the Isle of Wight, England. The tooth is worn beyond identification past Theropoda indet., but the CHR and CBR suggest it could be the basal carcharodontosaurian Neovenator. The basal tyrannosauroid Eotyrannus lengi is also another theropod found in this deposit, but is considered extremely rare. The majority of non-spinosaurid medium-sized theropod teeth from the Wessex Formation are assumed to be Neovenator.

A dinosaur tooth of an undescribed carcharodontosaurian, possibly a cf. Siamraptor suwati from the Grès supérieurs Formation in the Savannakhet Province of Laos. This species is currently only known from the equivalent Khok Kruat Formation in Thailand.

A dinosaur tooth of an Eocarcharia dinops from the Elrhaz Formation in Gadoufaoua, Niger. This species is often erroneously replaced or mistaken with the younger and much larger Carcharodontosaurus in media when featuring its contemporary genera such as Ouranosaurus or Sarcosuchus.

A dinosaur tooth of an indeterminate carcharodontosaurid from the Grès supérieurs Formation in the Savannakhet Province of Laos. It could possibly belong to cf. Siamraptor suwati, but the size and morphology seems to indicate a more derived species more similar to Carcharodontosaurus. Crown height of this tooth is around 3.2 inches (81mm) with a CBL of 33mm and CBW of 15mm. Midline mesial and distal serration density around 11.5/5mm, with the mesial carinae extending to the base. So a DSDI of 1.0, CHR of 2.45, and a CBR of 0.45.

A partial dinosaur tooth of an indeterminate theropod from the El Mers Group in Boulahfa, Boulemane, Morocco. The tooth notably shows pronounced interdenticular sulci or grooves in between the denticles on the distal carina. The short mesial carina could suggest a megalosauroid, but could also be a basal allosauroid as well.
