NICE 2.25" Spinosaurus aegyptiacus ToothMiddle Cretaceous MoroccoItem DescriptionDescriptionNICE TOOTH WITHOUT ANY REPAIRS! SHOWING INTACT ENAMEL IN GORGEOUS RICH BROWN COLORS.Spinosaurus was the biggest of all the carnivorous dinosaurs, larger than Tyrannosaurus and Giganotosaurus . It lived during the middle of the Cretaceous Period about 112 million to 97 million years ago, roaming the swamps of North Africa.Two Spinosaurus species have been named based on the region where they were discovered: Spinosaurus aegyptiacus (Egyptian spine lizard) and Spinosaurus maroccanus (Moroccan spine lizard).Two species of Spinosaurus have been named: Spinosaurus aegyptiacus (meaning "Egyptian spine lizard") and Spinosaurus maroccanus (meaning "Moroccan spine lizard")The first described remains of Spinosaurus were found and described in the early 20th century. In 1912, Richard Markgraf discovered a partial skeleton of a dinosaur in the Bahariya Formation of western Egypt. In 1915, German paleontologist Ernst Stromer published an article assigning the specimen to a new genus and species Spinosaurus aegyptiacusFragmentary additional remains from Bahariya, including vertebrae and hindlimb bones, were designated by Stromer as "Spinosaurus B" in 1934Stromer considered them different enough to belong to another species, and this has been borne out. With the advantage of more expeditions and material, it appears that they pertain either to Carcharodontosaurusor to Sigilmassasaurus.S. maroccanus was originally described by Dale Russell in 1996 as a new species based on the length of its neck vertebrae. Specifically, Russell claimed that the ratio of the length of the centrum (body of vertebra) to the height of the posterior articular facet was 1.1 in S. aegyptiacus and 1.5 in S. maroccanus. Later authors have been split on this topic. Some authors note that the length of the vertebrae can vary from individual to individual, that the holotype specimen was destroyed and thus cannot be compared directly with the S. maroccanus specimen, and that it is unknown which cervical vertebrae the S. maroccanus specimens represent. Therefore, though some have retained the species as valid without much comment,most researchers regard S. maroccanus as a nomen dubium or as a junior synonym of S. aegyptiacus.Location: Tegana Formation, Kem Kem Beds (Northern Sahara Desert), MoroccoSpinosaurus teeth are usually all over the place for sale.... large (over 3 inches), well-preserved examples without any repair can be quite rare. These large Spinosaur teeth often times will be heavily restored or repaired....If i believe I have one that fits the parameters of a repaired tooth...I'll state that in the description. This tooth appears to be quite clean.Identification conducted and confirmed by one of the premier collectors in the region Mohammad FadelQUICK NOTE:Most fossil pieces sold have teeth embedded by local craftsmen in matrix taken from Sahara Desert in the Oulad Abdoun Basin near the Khouribga phosphate plateau region of Morocco, North Africa. THE ONLY STRUCTURES that are natural are the teeth..The root area and jaw regions are "modeled" to represent this region of the tooth. The bones found in that particular region are pieced together to "represent" the jaw AND tooth rooth of this marine reptile....the bones could be anything...from actual Mososaurus, Plesiosaur bones to Enchodus bones. Rarely will a collector find teeth and jaw even remotely close to this.. This representation is great for someone starting out collecting fossils....the teeth are real....the rest is for the most part fabricated from pieces of bone. Still pretty cool though.We offer shipping discounts for multiple items and other listing combined.We ship by the combined weight that makes up the shipping box or container.
