{"product_id":"fossilized-dinosaur-tooth-hn998","title":"Albertosaurus sarcophagus tooth 1.8\" (4.5 cm), Drumheller, Alberta, Canada (disposition #001590)","description":"\u003cp\u003eThis is a nice \u003cstrong\u003e1.8\"\u003c\/strong\u003e (\u003cstrong\u003e4.5cm) long \u003cem\u003eAlbertosaurus sarcophagus\u003c\/em\u003e tooth\u003c\/strong\u003e from the \u003cstrong\u003eDrumheller area of Alberta, Canada\u003c\/strong\u003e. The lighter colour of this tooth indicates it had eroded out of the rock and was exposed to the elements for a length of time. This process essentially \"bleaches\" the fossil to shades of tan and white. Teeth usually disintegrate quickly once exposed so this piece is well-mineralized to survive the severe temperature swings and precipitation of the Canadian winter. It is sharp with nicely-preserved serrations (denticles) on both the anterior and posterior cutting surfaces. I believe some reassembly has occurred with adhesives. I do like that part of the core is exposed on one side to give a peak into the interior of a tooth.\u003c\/p\u003e\n\u003cp\u003eThe specimen rests on Styrofoam base within a golden box accompanied by a label reading “Dinosaur Tooth, Drumheller, Alta”. These particular golden boxes were used by Green's Rock \u0026amp; Lapidary in Calgary back in the late 1960s-early 1970s to sell dinosaur teeth prior to the introduction of fossil legislation in Alberta. Harvey purchased this tooth from Green's during that time period.\u003c\/p\u003e\n\u003cp\u003eThe rocks exposed in this area are from the \u003cstrong\u003eHorseshoe Canyon Formation\u003c\/strong\u003e (believed to be\u003cstrong\u003e 68 - 73.1 million years old\u003c\/strong\u003e).
