Tetradactyl theropod isolated track
# **Features: **Amazing isolated large theropod track with printing of the four digits. Preserved *in situ*. **Reconstruction: **Hebert Bruno Campos (2015). **Measurements: **The scale bar has a overall length of 300 mm. **Localization: **https://goo.gl/uf2brB **About the model: **It was photographed individually using a digital camera model Nikon Coolpix P520. A total de 22 photographs (.jpg) of resolution of 300 dpi were used and processed by Agisoft PhotoScan, generating the 3D .obj file. ## > Hi, I'm Bruno. This is a remarkable theropod track from the Sousa beds of the Sousa Formation of NE of Brazil. Why will you save an old dinosaur print? Source: Objaverse 1.0 / Sketchfab
Fig. 3 in Distribution of the dentary groove of theropod dinosaurs: Implications for theropod phylogeny and the validity of the genus Nanotyrannus Bakker et al., 1988
Fig. 3. Proposed phylogenetic relationships of Nanotyrannus within Tyrannosauroidea with distribution of the theropod dentary groove on trees indicated with thickened bars. (A) Most parsimonious cladogram proposed by this study placing Nanotyrannus as sister to the Albertosaurinae. (B) Relationship sensu Currie (2003a) placing Nanotyrannus as sister to Tyrannosaurus. This tree requires 5 more independent losses of the dentary groove than the tree proposed in this study. (C) Relationship proposed by Brusatte et al. (2010) placing Nanotyrannus as a juvenile Tyrannosaurus. This tree requires 4 more independent losses than the tree proposed in this study and a loss of the dentary groove through ontogeny in Tyrannosaurus.
Fig. 1 in Distribution of the dentary groove of theropod dinosaurs: Implications for theropod phylogeny and the validity of the genus Nanotyrannus Bakker et al., 1988
Fig. 1. Lateral views of theropod skulls demonstrating presence or absence of the dentary groove. The dentary groove is present in the primitive theropod (A) Coelophysis bauri (NMMNH P-42200), as well as in the derived theropod (B) Compsognathus longipes (BSP AS I 563). The dentary groove is present in the tyrannosaurids (C) Gorgosaurus libratus (TCM 2001.89.1) and (D) Nanotyrannus lancensis ("Jane"; BMR P2002.4.1). The dentary groove is absent in both (E1) young (LACM 28471) and (E2) adult ("Sue"; FMNH PR2081) Tyrannosaurus rex. Arrows indicate the position of the groove, when present. Scale bars equal 5 cm.

Fig. 2. Cladogram of Theropoda modifed from Carrano et al. (2012). Thickened branches indicate lineages possessing the dentary groove, thin branches indicate lineages in which the groove is absent. Grayed-out braches marked with dashed lines indicate taxa without a known dentary. Circled numbers indicate sequence of losses of the dentary groove assuming maximum parsimony.

Scale bars equal 10 cm. Scales not available for A-C because these photographs were taken of specimens on display behind glass.
