This week’s Fossil Friday features a dicot leaf preserved in Paskapoo Formation sandstone (roughly 50 million years old), discovered in a Calgary neighbourhood.

Paskapoo sandstone is a common decorative rock across the city, and it often contains plant and bivalve fossils. Next time you see one of these distinctive stones, take a closer look - you might find a fossil!

A fossilized leaf impression in brown sandstone. The leaf itself is quite broad and the veins are clearly visible. It looks very similar to the leaf of an aspen or elm. Around many of the basal veins the colour is a much darker brown.

Ooh a lovely fossil. Doesn't look like an elm to me (don't those have a large number of parallel secondary veins, that is pinnate venation?) or an aspen (also based on branching of the veins, although I'm not as sure about that one). Someone who is more of a paleobotanist (or even botanist) than me would likely have more to say.

You're absolutely right! I don't think that this is either of those, it's more of a general shape / description. I did ask a palaeobotanist about it, but she told me that without more details the best that she could do was 'dicot'.
