This Spinosaurus tooth is MASSSSSSSIVE! What is even more impressive is the NEEDLE-SHARP tip which is unheard of on teeth this size. This enormous tooth would have come from the jaws of a Spinosaurus dinosaur the size shown in the Jurassic Park film. A single hairline fracture has been repaired and color has been restored but otherwise, this tooth is in amazing condition for its size. There is no fabrication or artificial extension of the length. This tooth comes from a full-grown adult Spinosaurus dinosaur. With such a large dinosaur, it is nearly impossible to find teeth in this size range that are not severely damaged and heavily worn considering the amount of food a they would have had to consume to sustain their large body mass.
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!
