Hello again – from Houston this time. Steven and I are back from Malta. It’s been a few days since we’ve posted about the trip. I’m not gonna lie – we were tired, y’all. People always ask what it takes to be a paleontologist – in addition to education and field experience, it also takes a lack of need for any kind of sleep. It’s a completely amazing experience, but they get up at 6 a.m. and they don’t go to sleep until after midnight – and that’s a long day of hiking up mountains and hanging off cliffs.
So, apologies for the delay, but we have lots more to share – starting with Roberta, the other brachylophosaur. (Besides Leonardo, that is.) She’ll be on display in the new Great Plains Dinosaur Museum (opening June 6 in Malta, MT – book your tickets now. Seriously – you won’t be disappointed), so she won’t be on display in Houston with Leonardo – but she’s a beautifully preserved specimen (as you can see), and we got the chance to see the process of preservation in action this week.
Roberta’s teeth are so well preserved, you almost want to brush them.
The fossils have been preserved in the ground for millions of years – but once you get them out, it’s important to retain that preservation. Montana is so dry that once the bones have been excavated, they can dry out, crack and fall apart very easily. So, every six months, a new coat of Vinac (essentially, glue) must be applied to prevent this from happening.
In this video, Kathy Zoehfeld Vinacs (yes, it’s one of those noun-verbs, like “Google”) Roberta’s skull, to stabilize the fossil before the move to the new museum.
You can see David prepping the other end of Roberta’s skeleton here. In each video, notice how the Vinac adds a visible, thin sheen, in comparison to the other bones that haven’t been coated yet. It soaks into all the pores and helps stabilize the bones, so they don’t begin to crumble.
More soon on Dak – the brachy that survived a T. rex attack!
