It has been a while since I last posted about our Moroccan adventure last year, (please excuse me) I've been rather busy in the collections and hosting students and researchers. I will bring you up to speed with some of that in later blogs!
Back to Morocco! We had been in Morocco for several days now and were loving every minute of it. Myself and Zoe will both be blogging about our trip to Goulmima as we both had strong interests in the area and the fauna. See Zoe's blog for her view of the day!
The day started off by looking around a fossil and mineral shop/museum which was attached to the hotel where we were staying. They had lots of great things and some great casts, if only I had enough room at home to have a Triceratops skull in my living room!

Some fish from Morocco available to buy in the fossil shop.
After we had left the museum we were on the road again. Everyday we were travelling to different localities and seeing something new. It was great to see so much of the Moroccan landscape, it was amazing. The geology and landscapes which we were driving through changed everyday.
Myself and Zoe ready for the day ahead!

Just one of the many pictures I have of the Moroccan landscape.
Zoe was definitely the most excited about the trip to Goulmima as you get lovely ammonites from there. I was also interested in going there as amongst the ammonites you get fish in calcareous nodules and I knew we had nothing from that area in the collections so I was intrigued to find out more about the site and what we could find.
We stopped at a few sites on our drive but we didn't find any vertebrate material. Our team found some invertebrate material, bits of shells and ammonites, so after a while we moved onto another site.

The next site, Asfla 2, proved to be more fruitful. We discovered partial pieces of ammonite and Plesiosaur bones, but still no fish. Althought they were only scrappy bits of Plesiosaur we still collected them as they will be useful in the handling collections and in the Angela Marmont Centre (where you can bring fossils to have them identified) in the Museum.

Our last stop was a village settlement where most of the residents make a living out of fossil hunting, particularly from Goulmima. The rocks here are Cretaceous in age - about 90 million years old. Here were were taken by our local guide and shown some amazing specimens. What particularly caught the eye of TEAM FISH were the famous fish in nodules to be found in Goulmima!
These fish are called Goulmimichthys and are part of the class of fish commonly known as ray-finned fish (you can still find ray-finned fish swimming in the seas today e.g. cod). These fish are elongate and had numerous small spiny teeth. Some of the specimens we saw even had some soft tissue preservation, which is amazing. It is very rare you get soft tissue (muscles, skin etc.) fossilised, as it is usually eaten by predators or rots away very quickly after the animal dies.
Goulmimichthys looks very similar to fish (Rhacolepis in particular) that are found in the Santana Formation in Brazil. There has not been a huge amount of research done on Goulmimichthys and because we do not have any fish material from that area in Morocco in the collection we decided to purchase all of the specimens that` you can see in the picture below. The other flatter fish you can see are Ichthyodectes, which had a large mouth with pointed teeth. It was a fast swimming predator at this time.
I am actually going to start doing a research project on these fish which I am quite excited about. We are going to have the specimens CT scanned. This is a powerful machine which allows us to look inside the nodules (similar to an x-ray) instead of cutting the nodules (and the fossil) in half. I have not done this before so I am looking forward to learning new skills. Hopefully by doing this we can better understand how Goulmimichthys relates to other fish like Rhacolepis from Brazil.
Fossil fish mostly in nodules collected from Goulmima. This picture does not do them justice, they are more beautiful when you see them for real!
We did very well visiting the local collectors and seeing what they had. We gained many new specimens for the Museum's collections and made some good contacts with the local collectors.
From here we headed to our next hotel and packaged up our specimens to be shipped back to the UK.
My next blog about Morocco will be a guest one from our ore curator who was with us talking about pretty pink minerals!
