Most geological collections we hear about in the news are the prettiest, oldest, youngest, largest, smallest, rarest, most expensive or have some exciting story related to them that ties them to the evolution of our planet. Dinosaurs, human remains and meteorites are particularly popular. Over the last year we’ve embarked on a major curatorial project rehousing something that is the opposite – an unglamorous collection of bags of crushed rock.
Curators Becky Smith, Helena Toman and Robin Hansen in protective equipment.
I’ll be explaining why the samples needed to be re-housed and most importantly why they are strategically important to the work of the Museum and needed to be kept for future reference. And also why we are all dressed up in protective equipment and why I had to learn to drive a fork lift truck! Continue reading →
The micropalaeontology team attended the annual conference of The Micropalaeontological Society in Lille last week. My wife thinks that conferences are just an excuse for drinking, but I keep telling her that this is only partly true.

Earlier this month one of our long term visitors Prof John Murray published a paper with Elisabeth Alve outlining the distribution of Foraminifera in NW European Fjords. The main purpose was to provide a baseline for assessing man’s impact on the environment.

Read on to hear how Prof Murray used our microfossil library and collections to support their observations and investigate other factors that could control the distribution of these important environmental indicators.
Elphidium williamsoni Haynes, 1973 is a foraminiferal species that has been used extensively in relative sea level and climate change studies, as it is characteristic of intertidal zones. Identifying this and other species of Elphidium has proven difficult because key morphological characteristics show a wide range of variation causing widespread confusion in determinations.

A study led by University of St Andrews PhD student Angela Roberts and recently published in the Journal PloSOne, has gone a long way to clearly define this important foraminiferal species. The study is based on measurements from Museum type specimens as well as genetic studies on contemporary material collected from the same location as the type specimens.
Earlier in the summer I tweeted a picture of a microfossil slide I made in 1997. On the back I had written that it was made while I was listening to England bowl Australia out for 118 in a cricket test match at Edgbaston, Birmingham.

The slide got me thinking about more important hidden notes I have found recently that relate to historical events and provide a context to the microfossil collection. This post examines evidence of a collector’s escape from a disintegrating ice floe, attempts to cover-up a major disagreement between two scientists and the sad end for a laboratory that led to my first job as a curator.
When I first came to the Museum I dreamt that one day someone would bring something in for identification that I would recognise to be a really important find. The contents of a consultancy sample back in 2005 helped to make my wish come true. This post tells of the discovery and subsequent publication of a significant species of early fossil fish from Oman that provides information on the origins and evolution of life on our planet, one of the main focus areas of Museum science.

Very occasionally I get consultancy rock samples sent to me for dissolving to find microfossils. This is so that we can provide the age for a rock formation or details about fossil environments or climate. And so it was that Alan Heward, then of Petroleum Development Oman (PDO), sent me a sample in 2005 for analysis to try to find age diagnostic conodonts. Conodonts are extinct phosphatic microfossils that look like teeth and are used extensively for dating rocks that are roughly 500-205 million years old.
