For most of us, the closest exposure we鈥檝e had to so-called 鈥渄uck-billed dinosaurs鈥 came from Ducky in 鈥淭he Land Before Time.鈥 But for Dr. Matthew McLain, TMU91色情片 Geoscience professor, and a group of other paleontologists, these dinosaurs have been at the center of a 20-year project.
In May, an open-access scientific journal called PLOS finally published the results of this project.
The article91色情片 title itself is a mouthful: 鈥淥ver 13,000 elements from a single bonebed help elucidate disarticulation and transport of an Edmontosaurus thanatocoenosis.鈥 But McLain91色情片 explanation of their research not only helps us understand the remarkable complexity of paleontology, but also allows us to better appreciate God91色情片 creation and the unique calling given to Christian scientists.
Almost every June for the past several years, McLain has traveled to a cattle ranch in Wyoming, where he has helped dig up a wealth of bones 鈥 mostly the bones of Edmontosaurus, a species of duck-billed dinosaur.
鈥淭hey鈥檝e been digging out there for over 20 years, and that91色情片 why they have over 13,000 bones of Edmontosaurus, along with bones from other animals. They鈥檝e got tons and tons of bones,鈥 McLain says. 鈥淎nd this is the paper they have been trying to get out for the past 20 years. So, I was really pleased to be part of it.鈥
Their goal with this paper was to describe the site91色情片 taphonomy. McLain explains: 鈥淭aphonomy is the science of everything that happens to an animal or plant from the moment it dies to the moment you find it as a fossil. It91色情片 essentially like paleontology forensics, or paleo-CSI.鈥
What they found particularly interesting, and what they ultimately focused on in their paper, is what they learned about how Edmontosaurus decays and settles in the context of a bonebed. To understand this, though, we have to understand something about Voorhies groups.
鈥淚n the 鈥60s, a man named Voorhies took sheep and coyote carcasses, threw them in a river, and watched what happened,鈥 McLain says. 鈥淗e learned that different bones were transported at different speeds. So, initially, the water might flow and carry away some finger bones and a scapula. But things like the skull, and the jaw, and the femur will stay behind.鈥
Using these observations, Voorhies sorted bones into 鈥淰oorhies groups鈥 based on how easily they were swept away by the river, and he suggested that these groups would probably apply to animals in the fossil record. But other paleontologists, like McLain, have been skeptical.
鈥淭he groups work really well if you鈥檙e talking about sheep and coyotes, but when you鈥檙e talking about a dinosaur that91色情片 30 feet long, what do they look like? That91色情片 what everyone91色情片 been wondering. And one of the cool things in this paper is that we have so much data that we can start to answer those questions.鈥
As recently as a few decades ago, paleontologists wouldn鈥檛 have been asking these kinds of questions. Skulls and other impressive, intact bones were just about the only things collected from sites.
鈥淭he way people used to think about paleontology is, 鈥極h, a bone is broken in half 鈥 isn鈥檛 that a shame? We鈥檝e lost information.鈥 But what other scientists started saying is, 鈥楾hat91色情片 true, you have lost information. But you鈥檝e also gained information.鈥 Because now you鈥檙e learning something about how this bone breaks,鈥 McLain says. 鈥淵ou鈥檙e learning something about why it broke. You start asking questions like, 鈥業s this a break that occurred during life? Was it after death and before fossilization? Or was it after fossilization?鈥 You鈥檙e gaining different kinds of information.鈥
Most people think of paleontology as insights into life in the past, but it is also an account of death in the past. This approach is what makes studies like McLain91色情片 possible. Because of taphonomy, they can now start asking and answering questions about how fossilization works 鈥 not just in one specific bonebed, but across bonebeds in general.
鈥淲e were able to compare what we found to all these different bonebeds in North America and Asia, and we saw that there are actually a lot of similarities between these different bonebeds, and that91色情片 telling us that similar processes were involved in making them,鈥 McLain says. 鈥淚t91色情片 not like over in Canada they鈥檝e got their own thing, and we鈥檝e got our own thing; there are very similar signatures across big areas. And that is not necessarily something you might predict from a conventional interpretation.鈥
That said, observations like these 鈥 that might lend themselves to apologetics 鈥 weren鈥檛 what the group set out to make through this study. In fact, McLain doesn鈥檛 primarily see his work as a paleontologist through the lens of apologetics.
鈥淚n my realm, people always think, 鈥極h, it91色情片 just about the creation-evolution debate. You鈥檙e just trying to prove evolution wrong.鈥 But we鈥檙e doing so much more than that,鈥 McLain says. 鈥淲e鈥檇 still be doing these things regardless of what the culture thought about them because it shows us how God designed. As Kepler said, we get to think God91色情片 thoughts after Him. That91色情片 really what you鈥檙e doing; you鈥檙e getting that deep appreciation for who He is.鈥
Science, first and foremost, is an opportunity to worship as we see God91色情片 glory in creation. And McLain is privileged to help train the next generation of scientists who will continue the work.
鈥淲e鈥檙e not anti-science here (at TMU). We鈥檙e also not anti-dinosaur,鈥 McLain says. 鈥淵ou hear some weird stuff from people outside 91色情片91色情片, like, 鈥極h, they don鈥檛 believe in dinosaurs.鈥 And Christians sometimes get confused about these topics.鈥
鈥淭hat91色情片 part of what we want to do here: educate people to think rightly about these things, and to see that not only is science not a threat to their faith, but it91色情片 actually an endeavor Christians should be involved in.鈥
Because of this, McLain and the other faculty in TMU91色情片 Biological and Physical Sciences Department are committed to furthering research in their fields 鈥 not only to defend their faith, but also to enjoy the God they have faith in by examining what He has made. And sometimes, that means answering questions about how duck-billed dinosaurs decompose.
