An article published today has identified evidence of mating claspers on trilobites from the Burgess Shale. The best analogy would be to current day horseshoe crabs. The significance the authors cited is that it shows sexual dimorphism (males and females of the same species look different) was already well developed in the Cambrian. Their conclusion was based on morphological analysis of the limbs under the 7th thoracic and 1st pygidial segments, which differ from the others and do not reflect feeding adaptations. The theory is that the only explanation is that they have been modified as clasp

Well it has finally opened to the public on December 4rth. "The new Dawn of Life Gallery" at The ROM is perhaps the best gallery on the planet covering the earliest life to the emergence of land dwelling creatures. I was fortunate to have a tiny part in the new gallery having prepared a number of the museums specimens and also having donated and sold them some pieces . Here is a tiny taste of what you can see in the new gallery. It will not disappoint.

How many Myllokunmingia specimens are known to science? I keep on seeing wildly varying numbers, ranging from 1 to close to 100, and I really want to get a straight answer.

I embarked on a two day excavation trip in an attempt to find the raptorial appendage of Anomalocaris but only came home with about 300 Olenellus schucherti heads, some worm burrows, Wanneria bodies and heads, three Tuzoia, an inarticulate Brachiopod and some possible hyoliths, sponges and cyanobacteria. I am hoping to head back soon and do a paper on the locality! Here are a handful of my coolest finds!

This arthropod is a Marrellomorph, a clade of strange looking stem-group arthropods known from the Cambrian Burgess Shale and the slightly older Kaili Fauna in China (Marrella), the Silurian Herefordshire Lagerstätte in England (Xylokorys), the Ordovician Basal Upper Fezouata Formation (lower Arenig, or lower Floian), north of Zagora in southeastern Morocco and the Caradoc (Upper Ordovician) in Bohemia (Furca) and the Devonian Bundenbach Shale in Germany (Mimetaster and Vachonisia). Marrellomorphs lacked mineralized hard parts, so are only known from areas of exceptional preservation, limiti
