Fossil Record at Ya Ha Tinda Ranch focus of Speaker Series

SS2018 Martindale

The March 1 session of the 2018 Royal Tyrrell Museum of Palaeontology’s Speaker Series is a presentation by Dr. Rowan Martindale, University of Texas, entitled “Mass Extinction, Oceanic Anoxia, and Major Paleoenvironmental Changes in the Early Jurassic: New Data from Ya Ha Tinda, Alberta, Canada.”

There were only three Early Jurassic Konservat Lagerstätten known in the world until an incredible diversity of fossil marine life was discovered at the Parks Canada Ya Ha Tinda Ranch. A Konservat Lagerstätte is a deposit of exceptionally preserved fossils where soft body parts are fossilized. The Ya Ha Tinda site is the first marine Konservat-Lagerstätte described from the Jurassic Period in North America.

The Early Jurassic was an extremely stressful time for marine communities. Dr. Martindale’s research at the Ya Ha Tinda site gives us new insights into the diversity, ecology, and biogeography of marine communities during a time of significant biological and environmental change.

In her presentation, Dr. Martindale will discuss the exceptional fossils at the Ya Ha Tinda site and the fossil record of community collapse during the Toarcian Oceanic Anoxic Event, a major global extinction. An anoxic event refers to times in the deep past when parts of the Earth’s oceans were depleted of oxygen—devastating marine communities.

The Royal Tyrrell Museum’s Speaker Series talks are free and open to the public. Presentations are held every Thursday until April 26 at 11:00 a.m. in the Museum auditorium. Speaker Series talks are also available on the Museum’s YouTube channel:

20180216 Gr.2 Random Acts of Kindness TJH 0110

Jody Poland’s Grade 2 class of Greentree School participated in Random Acts of Kindness Day at Tim Hortons on Friday, February 16. Students made little notes with words of encouragement attached to a single lollipop which was then handed out to customers at the drive-thru window and throughout the restaurant. That kindness was returned as two customers in particular bought the students hot chocolate and a box of donuts.

Good deeds pay off for local charities

    Students at St. Anthony’s have been excelling as students and citizens in class, and in being rewarded, they passed their goodwill onto community charities.

    Teacher Anton Siaotung has introduced the green chips system to his classes.
    “This green chips system works on the premise that each student must respect, love, and serve one another, the school, and the community they live in,” he said.
     Since the beginning of the school year, students in his five classes have done a variety of good deeds, including helping each other in class, engaging in discussions, taught specialized topics in class, including subjects that could help to solve global problems including  elevating world poverty.
     “As an advocate for balanced intrinsic and extrinsic motivations, I rewarded them for their good deeds,” said Siaotung.

    For these good deeds, the students were awarded green chips, and already each of his five classes earned 500 chips. These were monetized and the students were rewarded $1 for 10 green chips. An anonymous donor stepped up to fund the program.
    Principal JoAnne Akerboom told The Mail initially the students would be rewarded with a pizza party in class. However, the students took the project one step further and donated the money to local charities.  
    His four Grade 8 and 9 classes donated the funds to the Drumheller and District Humane Society, for a total of $200, while his Math 30-1 class donated the $50 it earned to Habitat for Humanity.
