Lecture Highlights:
Greenland has recently been at the center of geopolitical discussions due to its strategic location and potential natural resources. Both natural and human resources of the world’s largest island will become increasingly important as warming climates allow greater habitation, increased mineral exploitation, new shipping routes, and heightened geopolitical relevance. Yet the geologic and glacial histories of Greenland remain underappreciated by many in the geoscience community. To achieve a better informed geocitizenry, Drs. Flemming Mengel and Bradley Markle will provide an overview of the 3.8 Ga geotectonic evolution of the crust underlying the world’s second largest continental ice sheet, the conditions that lead to its current glacial state, and what that ice can inform us about earth’s past and future climates.
Speakers
Dr. Flemming Mengel, Geological Sciences, CU Boulder
Dr. Flemming Mengel has worked extensively on the tectonic evolution of west Greenland and Labrador during and after receiving his PhD at Memorial University, St. John’s, Newfoundland, in 1988. He has published widely on tectono-metamorphic evolution of the Paleoproterozoic Nagssugtoqidian orogen. He also has years of experience in conventional and unconventional oil and gas plays focused in Rocky Mtn basins. He is currently a lecturer at CU Boulder.
Dr. Bradley Markle, Geological Sciences & INSTAAR, CU Boulder
Dr. Bradley Markle studies Earth’s climate system, how it works, and how it changes through time. His research specialties include isotope biogeochemistry; paleoclimate and climate dynamics, particularly in the high latitudes. He uses those tools to investigate geochemical proxy records and models of paleoclimate and climate dynamics. He received his PhD at the University of Washington, Seattle, in 2017 and currently holds positions in the CU Boulder Geosciences department and the Institute for Arctic & Alpine Research.

CSS May Meeting and Emmons Lecture
Spicomellus: extreme armor in the world’s oldest ankylosaur
Thursday, May 21, 2026
Dr. D. Cary Woodruff, Phillip and Patricia Frost Museum of Science, Miami, FL
In-person Meeting at Calvary Church, Golden
The link to Join the Zoom meeting will be posted here before the meeting.
Speculative rendering by Matt Dempsey
Lecture Highlights:
The ankylosaur Spicomellus afer is truly one of the most bizarre dinosaurs discovered to date. Covered head to tail with elaborate osteoderms, including cervical spikes nearly a meter in length, Spicomellus looks more Hollywood kaiju than factual dinosaur. However, it’s not just the appearance of Spicomellus that makes it unique. The construct of its bizarre armament is unlike any other vertebrate—extinct or extant. Being from the Middle Jurassic, Spicomellus is also the oldest ankylosaur thus far known; and with this bizarre body armor, is rewriting the functional and evolutionary role of armor in this dinosaurian clade. Spicomellus, along with other Gondwanan clades found within the El Mers Group, are helping to further push back, and elucidate, the origins of several dinosaurian lineages.
Speaker Background:
Dr. Cary Woodruff is the Curator of Vertebrate Paleontology at the Phillip and Patricia Frost Museum of Science in Miami, Florida where he is building a dinosaur collection from scratch. Cary has published numerous scientific papers involving taphonomy, histology (microscopic anatomy), dinosaur vision, fossil laws and regulations, dinosaur biomechanics, ontogeny (growth and development), soft-tissue preservation, dinosaur behavior, and human-fossil interactions. Cary’s main research specialization is dedicated to sauropod (“long-necked”) dinosaurs studying everything from how long it took them to grow up, how their skeletons changed during growth, how they moved their enormous bodies, how they behaved, how they fed, what their anatomy was like. Cary has also published a number of books on dinosaurs for kids.

Lowest parking rate is $5.75 for three hours; one pays using a QR code shown on signs there. For that parking rate, it says one is supposed to park on the upper (roof top) level. When driving uphill (southwest) on 14th St, the rooftop entrance is the 2nd entrance to the parking structure, immediately before the church.
For free parking: 14th Street usually has parking within a block of the entrance to the Church. Coming from the north (CO 93) or northeast (CO 58, between North and South Table Mountains), come southeast on Washington Street, turn right (southwest) on 13th Street, Turn left on Cheyenne St. Go up the hill and turn right on 14th Street. Park on your right.
Coming from the east or or southeast on US 6 (6th Ave.), exit US 6 onto 19th St. going NE. Turn left on Illinois St. Go through the Mines campus and turn right on 14th St. If you can, park NE of Cheyenne St.
When 14th Street is full, Mines may have scheduled an event.
There is Golden city parking southwest of downtown Golden. This is downhill from (northwest of) the Church in the half block between 13th and 12th streets, between Arapahoe St. on the SW and Miners Alley on the NE. There is usually space here. The Foss Lot (SE half of the parking area) is private and says “Paid Parking”. The public Arapahoe Lot (NW half of the parking area) says “Paid Parking 7-5” and should be free.
To get to the meeting, go up the hill along the church by Arapahoe St.

CSS Past Presidents’ Dinner and September Meeting
Thursday, September 10, 2026
Karen Chin, University of Colorado, Boulder
Geological Sciences and CU Museum of Natural History
Dinner and Talk at Mount Vernon Canyon Club
Dr Karen Chin
Research
My research investigates the structure and dynamics of ancient ecosystems–particularly those of the Mesozoic Era (about 65 to 250 million years ago). I am interested in how ancient communities of organisms differed from modern ecosystems in composition and organization. Much of my work focuses on tapping information available in permineralized coprolites (fossil feces), but I also examine other trace and body fossils. My work focuses on understanding interactions among ancient organisms, and deducing the environmental conditions in which these organisms lived and were fossilized. I use a multidisciplinary approach by examining geological, biological, and chemical characteristics of fossils and compare the fossil evidence with modern ecosystems to derive paleoecological interpretations.

About the Colorado Scientific Society
The Colorado Scientific Society was founded in 1882 as a forum for the exchange of observations and ideas on the topics of earth science. Lecture topics largely focus on earth science, and are open to the public. In addition to our monthly lecture series, the society is also active in public service. We fund student research grants, construct and post signs that describe local geologic features, and organize and lead field trips.
The Colorado Scientific Society normally meets on the third Thursday of the month from September through May. (In the summer months of June-August, too many members are out in the field.)
6:30 – Social time at in-person meetings
6:45 – Join Zoom meetings
7:00 – Meeting and Program begin
The Colorado Scientific Society is an Associated Society of the Geological Society of America
