This Spinosaurus tooth is from a full-grown MASSIVE dinosaur! If it was not for the feeding wear on the tip, this tooth would have measured 4.5 inches and would have been in the jaws of a Spinosaurus the size shown in the Jurassic Park film. To hold this tooth in your hand is impressive to say the least! The heavily worn tip and massive thickness demonstrates the endless amount of kills and meals such a large dinosaur would have had to make to sustain its enormous body weight. There is a single fracture repair on this incredibly impressive specimen but there is no fabrication or artificial extension of the length.
WARNING: A common trick to fake large dinosaur teeth in the market is to attach either a bunch of sand mixed with glue on the end of the tooth's root to exaggerate the length or even worse, fabricate a giant impressive tooth by combining and blending multiple teeth sections together to appear as one massive tooth or to fabricate the bottom portion of the tooth and extend, by a much as DOUBLE OR MORE, the original length of the tooth before work started. The workmanship of a few notorious United States-based fakers is of the finest workmanship and VERY convincing in appearance. There have been European fakers also known to create and sell these large teeth. Don't be fooled when you are shopping for large dinosaur teeth of ANY SPECIES, not just Spinosaurus. These are common practices of both unscrupulous and uninformed dealers. We see these "doctored" large dinosaur teeth offered quite frequently and numerous junk, worthless teeth that have been converted and heavily modified are selling for ridiculously high prices, mostly at shows and on the internet. Ebay is one of the worst places for this where fraud runs rampant and unchecked in the entire rare collectibles field but some fossil show dealers and internet sites have been pawning these "creations" off for years now, as well!
