Chenanisaurus

Fossilized dinosaur tooth from a very rare Chenanisaurus theropod.
  • Species: Chenanisaurus barbaricus
  • Catalogue ID: TYI-MAR-8503-3375
  • Formation: Couche III
  • Age: Upper Cretaceous (Maastrichtian)
  • Provenance: Oued Zem, Ouled Abdoun Basin, Morocco
  • Size: 31.5mm
  • Details: Mesial Density 9/5mm; Distal Density 9/5mm
  • Condition: No repair or restoration; stabilized with Polyvinyl butyral (PVB) in acetone

Chenanisaurus is one of the more unusual theropods occasionally seen in the market. The rare dinosaur material found in the phosphate deposits of Morocco are hypothesized to have been animals washed out to sea. This species of large abelisaurid was one of the last non-avian dinosaurs and may have witnesses the mass extinction at the end of the Maastrichtian.

Majungasaurus

Fossilized dinosaur tooth from a Majungasaurus theropod.
  • Species: Majungasaurus crenatissimus (syn. Majungatholus atopus)
  • Catalogue ID: TYI-MAD-6956-4305
  • Formation: Maevarano Formation
  • Age: Upper Cretaceous (Maastrichtian)
  • Provenance: Berivotra, Mahajanga Province, Madagascar
  • Size: 27.4mm
  • Details: Mesial Density 9/5mm; Distal Density 11/5mm
  • Condition: No repair or restoration; stabilized with Polyvinyl butyral (PVB) in acetone

This is an isolated tooth from a Majungasaurus, one of the last non-avian dinosaurs to ever roam this planet. The teeth of this species is similar to that of other large bodied abelisaurids like Chenanisaurus and Carnotaurus. Despite being an abundant species, supply is now limited as Madagascar no longer allows for the export of fossil material other than invertebrates which must be processed (polished, cut, etc) in someway. These specimens can also be seen labeled as Majungatholus atopus and Majungatholus crenatissimus, but all refer to the same species.

Timurlengia

Fossilized dinosaur tooth from a Timurlengia theropod.
  • Species: Timurlengia euotica
  • Catalogue ID: TYI-UZB-2813-4962
  • Formation: Bissekty Formation
  • Age: Upper Cretaceous (Turonian)
  • Provenance: Dzarakuduk or Uchkuduk, Kyzylkum Desert, Uzbekistan
  • Size: 43.2mm
  • Details: Mesial Density 16/5mm; Distal Density 16/5mm; CH ±41mm; CBL 13.8mm; CBW 7.1mm
  • Condition: No repair or restoration; stabilized with Polyvinyl butyral (PVB) in acetone

This is a Timurlengia tooth from the Kyzylkum Desert of Uzbekistan. The tooth has undulations similar to those seen in carcharodontosaurids which can make it easily mistaken for the contemporary, Ulughbegsaurus uzbekistanensis. Because the teeth of Ulughbegasaurus are not known (only inferred by its alveoli), it's possible that some teeth currently assigned to Timurlengia may in fact be this basal carcharodontosaurian. These basal pantyrannosaurid teeth along with other Bissekty material were commonly seen in the market a while back, but have since mostly vanished from the market. The likely reason was that most if not all of the material that was seen came from a single old collection. It's unknown if new material is even being gathered at all.

Dromaeosaurus

Fossilized dinosaur tooth from a Dromaeosaurus raptor showing the mesial twist of the carinae.
  • Species: Dromaeosaurus albertensis
  • Catalogue ID: TYI-USA-0930-2394
  • Formation: Judith River Formation
  • Age: Upper Cretaceous (Campanian)
  • Provenance: Hill County, Montana, United States
  • Size: 13.5mm
  • Details: Mesial Density n/a; Distal Density 18/5mm; CH ±12mm; CBL 5.9mm; CBW 3.3mm
  • Condition: Has repair, but no restoration; stabilized with Polyvinyl butyral (PVB) in acetone

Dromaeosaurus albertensis is the original or first "raptor" described, hence why this clade is collectively known as the dromaeosaurids. The dentition of these bird-like predators share some similarities to small teeth of tyrannosaurids making it difficult to distinguish upon a quick glance. The most notable feature that defines this particular tooth as Dromaeosaurus is the lack of serrations of the mesial carinae and the strong mesial twist. The tooth also has chisel-like denticles which distinguish it from the more common Saurornitholestes.

Grès supérieurs Baryonychine

Fossilized dinosaur tooth from an unknown spinosaurid dinosaur with serrations under a macroscope.
  • Species: Baryonychinae indet. (?)
  • Catalogue ID: TYI-LAO-5316-1046
  • Formation: Grès supérieurs Formation
  • Age: Lower Cretaceous (Aptian-Albian)
  • Provenance: Savannakhet Province, Laos
  • Size: 27.3mm
  • Details: CH ±23mm; CBL 10.6mm; CBW 9.1mm; ±33 ridges on both sides including both carinae
  • Condition: No repair or restorations; stabilized with Polyvinyl butyral (PVB) in acetone

A possible baryonychine from the Grès supérieurs Formation. However, given the more basal position of the spinosaurids in the region, it's possible some tooth positions of these genera had serrations. Even derived teeth from Spinosaurini indet. from the Kem Kem Beds can occasionally show serration-like characteristics.

Afrovenator

Fossilized dinosaur tooth from a large Afrovenator with heavy fractures across the entire tooth.
  • Species: Afrovenator abakaensis
  • Catalogue ID: TYI-NER-6542-9930
  • Formation: Tiourarén Formation
  • Age: Middle Jurassic (Bathonian-Oxfordian)
  • Provenance: Marandet (Marandade), Aderbissinat, Agadez, Niger
  • Size: 62.4mm
  • Details: Mesial Density 9-10/5mm; Distal Density 11/5mm; CH ±54mm; CBL ±25.5mm; CBW ±13mm
  • Condition: No repair or restorations; stabilized with Polyvinyl butyral (PVB) in acetone

This is an exceptionally large Afrovenator tooth from the Middle Jurassic. This particular specimen was stated to come from "Marandade" which is most likely referring to Marandet. If correct, this likely comes from the true Tiourarén Formation with a heavily fractured and glossy preservation common to that deposit. This species of theropod at one point used to be very rare on the market, but a decent number of these Middle Jurassic dinosaurs were available a while back. While these fossils are still readily available (or not, depending on when this is being read), the supply will likely dry up, or the quality will drop significantly as fossils from Niger can no longer be exported. It is also important to keep note of where each specimen supposedly came from as the provenance is inconsistent and all over the place.
