A team of geologists from the Museum and Imperial College are in Mexico carrying out  fieldwork at two of the most active volcanoes in the world: Popocatépetl (Popo) and Colima. Catch up with their adventures in this series of blogposts.

 

This uncomfortably oblique photograph marks the end of this year’s fieldwork at Popo. As you can see, we have been extraordinarily successful in collecting samples:

All in all, we have collected twelve boxes full of pumice and lava in the last two weeks, each of them weighing about 20 kg!

 

Moreover, not only have we been doing well in bagging rocks, but we also made many important field observations, such as the relation of the different volcanic units in time and space. This is essential for the proper handling and analysis of our samples.

 

As soon as our heavy load arrives at the Natural History Museum, I will crush the rocks into tiny pieces and examine them using different types of microscopes. We are confident that this will tell us intriguing stories about how Popo works. The adventure has just begun!

 

But first, we will drive this trunkful of rocks to Mexico City, where we will also say ‘muchissimas gracias’ and ‘hasta luego’ to Julie, who will fly back to London, and also to Hugo and Guillem, who will stay in Mexico City. Chiara and me will stay in Mexico for another week, which we will mostly spend in Colima. There, about 500km West of Popo, the ‘Fuego de Colima’ volcano is currently very active, with several small eruptions every day. We are excited to go there and see some nice ashclouds, and of course, we will keep you posted about our ventures in West Mexico!

The Lyme Regis Fossil Festival took place in Dorset on 2-4 May 2014. Our palaeontologists Lil Stevens and Zoe Hughes report back from a weekend of sun, sea, fossils and fun.

 

Saturday in the festival marquee was a busy one with lots of people queuing to sieve for sharks teeth from Abbey Wood (which they got to keep!).

Elsewhere Museum staff were also quite busy. Mark Spencer and the Angela Marmont Centre (AMC) team were talking about seaweed using samples which they had collected from the beach that morning.

Emma Bernard’s shark measuring activity proved very popular - she had crowds of rapt people hanging onto her every word. People like big Megalodon teeth! Emma has also been busy tweeting for @NHM_FossilFish.

Andrew Briscoe and Suzanne Hocking have been teaching people how to extract DNA from strawberries- incredible that this can be done in a marquee on the beach!

In the rest of the marquee lots of other organisations had some great activities. Zoe Hughes discovered that she walks like a Velociraptor with Plymouth University and that she is as tall as an extinct fossil penguin from Antarctica with the British Antarctic survey.

We've packed the car and we're ready to go to this year's Fossil Festival! The Museum will be in its usual place in the main marquee on the beach near the Lyme Regis Museum - this is my first trip to Lyme so it's all new to me.

 

I'm looking forward to the tropical climate and warm, shallow sea...oh no, that was in the Jurassic period. Forecast for this weekend: cool with occasional showers and the possibility of overnight frosts. Ah well, we're in a tent!

Museum volunteers Sam McCausland and Mike Smith pack the important stuff into the Fossilmobile.

 

This year we will be bringing anthropologist Margaret Clegg to talk about ancient humans, and palaeontologists Pip Brewer and Jerry Hooker to showcase some very ancient mammals.

 

You can sieve for sharks teeth with fish curator Emma Bernard and expert David Ward, and if you can find them you can take them home with you! They will also show you how to use shark jaws and teeth to estimate the body size of some of the largest sharks ever to have lived.

 

Zoe Hughes, our cephalopod and brachiopod curator and I will be explaining how palaeontologists reconstruct fossils to work out how the animals looked when they were alive. Test your palaeo-skills with our drawing challenge! Palaeontologists Martin Munt and Noel Morris are Lyme veterans and will be on hand to answer all your most technical paleontological questions - so you'd better think of some!

 

Those mysterious Museum mineralogists are planning a sparkling surprise so come down to the beach and see some very special pebbles...

It was our first day at the festival proper yesterday, and the weather was great!

 

We had a day of great interactions with local primary schools. Scientists from the Museum brought along a massive cast of a baryonyx skull, and visitors were invited to take a closer look at some microscopic life through one of our amazing scanning electron microscopes (SEM).

Other great exhibitors included:

 

  • The Buckland Club, who invited the public to help excavate a model plesiosaur
  • Rock Watch, running creative plasticine fossil workshops
  • The University of Plymouth, who measured visitors' strides to work out which dinosaur they are most like
  • a great collaborative artwork of the Jurassic coast, led by artist Darrell Wakelam

Here's hoping for some good weather this bank holiday weekend! More news from the learning team soon.

The Museum learning engagement team's first day at the Lyme Regis Fossil Festival ended yesterday and it was an epic day!

 

We were up at 6.30 to start at 8 yesterday at Thomas Hardye School, where five schools from the Dorset area participated in earth science related activities throughout the day. The team have been helping students investigate a dinosaur dig and identify what they uncover.

Other activities included creating meteor impact craters and extracting copper from malachite using electricity!

Scientists from the Museum brought lots of amazing specimens for the 450 students, including tektites, formed from sand rapidly heated by meteorite impacts and ejected to form these beautiful tear drops shapes.

Other highlights included the biodiversity team's activity, where students identified bugs and other arthropods, contributing to important citizen science data. There was also a great stand featuring Thomas Hardye's very own Fossil Club, who were busy inspiring fellow students to get into fossils.

 

We finished packing up, headed to Lyme Regis to set up for the festival on the water front and today's primary school day, (and finished off with some well earned fish and chips!)

 

The festival runs from today until Sunday 5 May so if you're in the area come and join us and many other exhibitors for more earth science fun!

Yesterday, we went to a secondary school in Dorchester. We set up our stand along with several others from the Museum, local fossil groups and the school's fossil club. At our stand we were giving students a brief explanation of taxonomy (how you classify all living things), specifically cephalopods.

 

We explained the difference between three major groups of cephalopod: ammonites, belemnites and nautiloids. The belemnite phragmacone we found yesterday proved to be very useful in explaining how a belemnite dealt with buoyancy control. The children enjoyed examining the recent nautilus we had with us to locate the hole for the siphuncle.

After the school event we returned to Lyme Regis to help set up the tent for the main event: the Fossil Festival. Our main earth science table is set up, with specimens for the public to handle starting today. We constructed the Baryonyx skull and helped David Ward set up his shark sieving activity.

Today is the primary school day and we have been told approximately 600 children willl be visiting - wish us luck and we will report back soon!

The specimens are packed and tomorrow the first Museum staff will make our way down to Lyme Regis for the fossil festival (3-5 May). We have a nice selection of ammonites, brachiopods, fish, sharks, and a replica dinosaur skull of a Baryonyx and its claw to show people different types of fossils which can be found on the Jurassic Coast. We do seem to have a lot of things to take...

This first group is Martin Munt, Zuzanna Wawrzyniak, Zoe Hughes and me, Emma Bernard. We will be heading out to do some fieldwork on Wednesday (Hopefully we’ll find lots of ammonites!), though we haven’t yet quite decided where we will head to, it might be weather dependant, so hope for sunshine.

 

Thursday will take us to a school event in Dorchester where we will be talking about the wonders of cephalopod taxonomy. Over the weekend it is the festival and the Museum will be represented by many staff and lots of fun activities including sieving for sharks teeth, learning all about the wonders of the Rhynie Chert (which is 407 million years old) and gold panning. There is also an opportunity for people to bring along any fossils of their own for identification.

 

The festival is important as Lyme Regis is at the heart of the Jurassic Coast and is a UNESCO World Heritage Site.

Zoe and I will be posting updates all week here on our blog. Stay tuned!
