Scans of the teratological newt Triturus dobrogicus. (A) General overview of the skeleton. The teratological individual presents 17-paired ribs distributed in 11 vertebral bodies, plus an extra rib in the sacral region. (B) Detail of a normal T. dobrogicus specimen in dorsal view, showing the regular vertebral shape and location of ribs. (C) Dorsal view of the teratological specimen, showing the amalgamation of centra and the asymmetric distribution of ribs. The teratological specimen was collected in Velence, Pest County, Hungary (15/03/1967) by P. Bohn and placed in the Herpetology Collection of the Hungarian Natural History Museum (catalogue nr. 67.12.1.). The normal individual was collected in Kiskunhalas, Bács-Kiskun County, Hungary (21-23/03/1975) and placed in the Herpetology Collection of the Hungarian Natural History Museum (catalogue nr. 57.41.1.). The scans were taken with a NanoSPECT/CTTM In vivo pre-clinical imager (Bioscan Inc., Washington DC, US, manufactured by Mediso, Budapest, Hungary) on 55 kVp tube voltage, 0.145 mA tube current, and 1500 ms exposure time. The images were reconstructed with an exact cone beam method and with 50x50x50 μm3 voxel size. We used the software InVivoScope™ with maximum intensity projection to visualize the image. Scale bar in A = 0.5 mm; scale bars in B and C = 0.1 mm.
