However, the data is certainly not conclusive and as noted above, there are other causes of tooth abnormalities that are currently un-testable on dinosaur taxa (e.g., nutritionally induced anomalies). Further testing of the genetic polymorphism hypothesis seems warranted\"\u003c\/p\u003e","brand":"Stonesandbones","offers":[{"title":"Default Title","offer_id":52244749549855,"sku":"trex11","price":5500.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/4674\/9983\/files\/DSCF5336.jpg?v=1773429951","url":"https:\/\/www.stonesandbones.ca\/products\/2-01-rare-y-serrated-tyrannosaurus-tooth-judith-river","provider":"Stonesandbones","version":"1.0","type":"link"}
