Most of my research involves studies of shallow-water organisms from the Late Ordovician Period, about 455-444 million years ago. Over the years, my colleagues and I have produced a number of papers, research posters, and other media associated with this work.

1. *New* Our review of Ordovician Konservat-Lagerstätten in Manitoba has been published in Geoscience Canada (2012, volume 39, number 4, published in February, 2013). This was a group effort (Young, Rudkin, Dobrzanski, Robson, Cuggy, Demski, and Thompson), providing a status report on many years of field collecting and study.

2. This is a pdf of a paper co-authored with Whitey Hagadorn, about the jellyfish fossil record.  It was published in 2010 in Palaeoworld:

3. This is the pdf of a poster about Ordovician soft tissue preservation in Manitoba, produced for the International Palaeontological Congress in London early in the summer of 2010:

The Ordovician diversification didn’t only affect organisms with hard skeletons. Important information about Ordovician biodiversity is also hidden in the sparse soft tissue record. Ordovician lagerstätten are rare globally, particularly in comparison with the Cambrian. Manitoba has least three Ordovician sites with preserved soft tissue: at Cat Head, Airport Cove, and William Lake. Ongoing studies at these sites will significantly enhance our understanding of global Ordovician biodiversity. The Cat Head, of early Maysvillian age, is significantly older than the other two, which are considered to be Richmondian. Depositional environments also differ: the William Lake and Airport Cove biotas represent restricted marginal marine conditions, while the Cat Head was probably deeper water.
