{"product_id":"fossilized-dinosaur-tooth-hn1007","title":"Albertosaurus sarcophagus tooth 1.9\" (4.75 cm), Drumheller, Alberta, Canada (disposition #001590)","description":"\u003cp\u003eThis is a naturally-worn \u003cstrong\u003e1.9\" (4.75cm) long \u003cem\u003eAlbertosaurus sarcophagus\u003c\/em\u003e tooth\u003c\/strong\u003e from the \u003cstrong\u003eDrumheller area of Alberta, Canada\u003c\/strong\u003e. It has a slender, strongly curved profile with brown and tan coloration and wonderful enamel. A row of distinct serrations, or denticles, is preserved along both the posterior and anterior edges of the carinae. The tooth has been reassembled and is missing a few pieces. This is typical of teeth that show extreme natural wear like this example as they typically fall apart once exposed by erosion. Note the natural dark brown-coloured, lengthwise \"slice\" coming down from the tip. This indicates natural feeding wear of the enamel from chewing through bone and excites the imagination! This tooth has not been restored with any fillers and I would, personally, leave it that way so some internal features can be viewed and enjoyed. \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).
