Тема: Cave and karst news and announcements from NCKRI
COVID is increasing around the world again, and so there is not much news to share. I hope you and your loved one remain well through this crisis. Here is the news:
Student and Job Opportunities
- Summer Course: Puerto Rico’s Caves and Culture
- New Maya Cave Rock Art Report Available
- Sharks Added to the List of Mammoth Cave National Park Fossils, USA
Conferences and Meetings
- Announcing: 23rd National Cave and Karst Management Symposium, Texas, USA
- List of Upcoming Cave and Karst Meetings
Please contact the people and organizations listed below for more information, and feel free to share this message with anyone who may be interested.
Summer Course: Puerto Rico’s Caves and Culture
This summer course is designed to introduce students to caves, and their influence in Puerto Rican culture over millennia. Students will learn the fundamentals of cave development, the influence that caves have in Puerto Rican culture (and other Caribbean countries), and explore theoretical models to study the interaction human-geology. The tentative course dates are 25 May to 9 June 2021 and are subject to change.
The application deadline is 1 November 2020 so apply quickly by going to https://www.jmu.edu/global/abroad/programs/jmu-puerto-rico-geology.shtml.
New Maya Cave Rock Art Report Available
In the Realm of Rain Gods: A Contextual Survey of Rock Art across the Northern Maya Lowlands, is a new open access (free) report you can download from https://www.mdpi.com/2571-9408/3/4/61. The abstract of the report follows:
“Regional rock art studies have provided insight into the role of caves in Maya ideology and worldview. In addition to the content of the imagery itself, the placement or siting of rock art with respect to natural and cultural features within the cave environment can reveal much about the function and meaning of cave use practices. This comparative analysis of rock art emphasizes contextual considerations with a discussion on the spatial and symbolic relationships between images in individual caves. Rock art in the northern Maya lowlands is commonly associated with watery areas and pathways leading to pools in caves. Across the northern Yucatan Peninsula, watery caves witnessed the rites and rituals of religious practitioners who appealed to the rain gods. Rock art scenes throughout this region were often devised and positioned in ways that reveal or are consistent with this unique and pervasive emphasis on rain and agricultural fertility in religious practice.”
Sharks Added to the List of Mammoth Cave National Park Fossils, USA
A team of paleontologists, cave specialists, and park rangers at Mammoth Cave National Park have discovered a trove of fossil treasures that has yielded one of the most diverse Mississippian shark faunas in North America. At least 40 different species of sharks and their relatives have been identified, including six new species. Rare preservation of three-dimensional skeletal cartilage documented in Mammoth Cave allows us to understand the anatomy and relationships of these ancient sharks.
The discoveries in remote cave locations within the park were made during an ongoing paleontological resources inventory that began in November 2019. Mammoth Cave is known for a variety of ice age mammal fossils as well as ancient marine organisms.
The 325 million-year-old fossil-rich limestones of the Mammoth Cave System were formed during the Late Paleozoic, during a time period known to geologists as the Mississippian Period. The park staff reported a few fossil shark teeth exposed in the cave walls of Ste. Genevieve Limestone in several locations. Fossil shark specialist John-Paul (JP) Hodnett of the Maryland-National Capital Parks and Planning Commission was recruited to help identify the shark fossils, which were primarily teeth and fin spines. Since most of the skeleton of sharks is composed of cartilage, rather than bone, the skeletons of sharks are rarely preserved as fossils.
Hodnett and park staff, quickly discovered and identified many different species of primitive sharks from specimens in the rocks lining the cave passages in Mammoth Cave. More than 40 different species of fossil sharks and relatives have been identified from Mammoth Cave specimens in the past 10 months and the fossil survey continues. Among this fossil shark assemblage, there appears to be at least six fossil shark species that are new to science. Those species will be described and named in a forthcoming scientific publication.
Most of the shark fossils have been discovered in areas inaccessible to visitors on cave tours, but park staff are preparing photographs, artists’ renditions, and three-dimensional models for the visitors to view and explore in park exhibits. A new painting showing some of the Mississippian shark and invertebrate fauna from Mammoth Cave has been completed by paleoartist Julius Csotonyi and was premiered to the public on October 14 to celebrate National Fossil Day 2020:
In addition to this rich diversity of primitive sharks at Mammoth Cave, two partial cartilaginous skeletons of different species of sharks were also found within Mammoth Cave. One specimen was discovered by a caver with the Cave Research Foundation and the other has been known by the park guides for years. The preservation of cartilage in layers of Paleozoic rock is a very rare occurrence and moved the team to thoroughly document these specimens. National Park Service geologist Jack Wood lugged equipment through narrow cave passages to capture photogrammetric images of the two rare specimens. Wood produced 3-D models of the cartilaginous shark remains which are posted on the National Park Service website.
Paleontological resource inventories, similar to the one underway at Mammoth Cave National Park, have helped to document fossils in at least 277 different national parks throughout the United States. National Park Service Senior Paleontologist Vincent Santucci said, “Paleontological resource inventories are fundamental to the management of non-renewable fossils. These inventories enable us to establish baseline fossil data capturing the scope, significance, distribution, and management issues related to park fossils. Many new and important fossil discoveries are tied to field inventories, as demonstrated at Mammoth Cave National Park, expanding our understanding of the fossil record in the national parks.”
Announcing: 23rd National Cave and Karst Management Symposium, Texas, USA
I heartily invite all cavers, cave owners, cave conservancies, cave managers, cave researchers, and cave lovers to the 23rd biennial meeting of the National Cave and Karst Management Symposium (NCKMS), to be held in San Marcos, Texas on 1–5 November 2021.
Karst is a type of landscape featuring caves, sinkholes, sinking streams, and springs. Roughly 20%, or 53,720 square miles, of Texas is karst, including the urban corridor of Waco through San Antonio. NCKMS meetings are scheduled at different locations across the United States in order to highlight local karst resources and management issues. The last (and only) one held in Texas since their beginning in 1975 was in New Braunfels, in 1989. Our state’s population (and number of caves!) has grown rapidly since then, leading to inevitable management conflicts. Typical presentations and workshops during the week focus on research, resource management, stewardship activities, education communication, and sustainability. Sessions, field trips, and workshops often provide many examples in both show cave and wild cave resource management, and are open to the general public through day passes. Various tours, field trips, and other great activities are planned.
We hope to see you in the Texas Hill Country next November!
