Dinozor Fosillerinin Hazırlanışı

Fosil hazırlayıcıları, fosillerin doğal yollarla kırılmış kemiklerini ve dişlerini orijinal hallerine geri döndüren çok yetenekli teknisyenlerdir, bu biraz da sanat koruyucularının hasarlı tablolara ve heykellere yaptıklarına benzer.
Fosiller sahadan geldiğinde, alçı kılıflar içinde, etraflarındaki kaya veya matrisle birlikte bulunurlar. Fosil hazırlanması, alçı kılıfı açarak, fosilin etrafındaki matrisi kaldırmayı içerir.

Video açıklaması

this specifically is the skull of a dinosaur from a super family is called ankylosaurus they are the armored dinosaurs if you can imagine an armadillo with a lot of spikes all over it it's a common misconception that bones are dug in the field where they're found what actually happens is the researcher will be walking through you know deserted barren Canyonlands looking for bones sticking out of the rocks or weathering out a trench is dug around the the specimen then it is wrapped in bandages soaked in plaster which is what you see here so this is straight from the field where it was found in Mongolia for this kind of material I would use small tools like these needles and things like that and some brushes to slowly work off the rock from the bone this is soft enough where I can use these kind of needles and things like that so kind of gently worked it off we're basically chipping away till we get to the surface of the bone and then what we're doing from there is following the line of the bone around gradually removing the rock as we're doing so so I'm doing is essentially just using this needle so softly work off the surface of the rock so I get to the layer of bone underneath I've been working on this piece already about five months already and it's probably gonna take me another three or four to get it to the condition that the researchers wanted in every year these researchers go out to the field and collect hundreds of specimens and they bring them back here to the museum a lot of times we just find pieces like you see here these are just broken pieces of bones of individual dinosaurs and things like that but once in a while we do get whole dinosaurs and this tells us very much about the anatomy this is how we know how certain dinosaurs were actually how their bones were arranged and things like that using a silicone rubber we've actually made a mold of the skull here and then filling it in with an epoxy resin we basically make a copy of the skull you can see here and this is research quality you can take this on their CT scanner and it will literally have all of the folds and wrinkles and cracks of the original specimen we'll take pop about four copies of each bone that we do one scientific quality cast another one for the home institution so whatever country we've gotten it from they'll get a copy of it as well somebody will sit here and literally block out these pieces put them back together and then mold the whole thing all together and get this this pass that you see here
