The Tully Monster

The Tully Monster

Nobody knows what the Tully Monster was. Consequently it is the State Fossil of Illinois, the state in which it was discovered by Francis Tully in the 1950's. It lived about 300m years ago.

Is it a vertebrate or an invertebrate? The answer may lie in its (very odd) eyes! Did you know that there was zinc and copper in eyes and their ratio differs between creatures with backbones and those without.

You can read all about it in THIS ARTICLE. The reconstructions certainly look odd!

NEXT WEEKS EVENTS

11th to 17th November 2019


THE FOLLOWING IS AN EXTRACT FROM BRISTOL AND WEST COUNTRY GEOLOGY CALENDARS

MORE DETAILS CAN BE FOUND IN THE BRISTOL AND THE WEST COUNTRY CALENDARS AND ON THE WEB SITES OF THE RELEVANT SOCIETY OR ORGANISATION.


MONDAY 11TH

Geostudies - Lecture Series - Ordovician
When
Mon, 11 November, 19:30 – 21:30
Where
Wynstones School, Stroud Road, Whaddon, Gloucester (map)
Description
Geology of the Ordovician Period. 

The last Phanerozoic geological period to be named, after a bitter struggle between Murchison and Sedgwick. Lasting from 
485 to 444Ma ago, this period saw the enormous radiation of new forms of life and the earliest colonisation of the land by primitive plants “The Great Ordovician Biodiversification Event” . The two halves of Britain were separated by the Iapetus Ocean, but both were tectonically extremely active. The supercontinent of Gondwana drifted across the South Pole, possibly triggering a short and unusual (high CO2) glaciation and the second biggest mass extinction of life at the end of the period. As usual there is considerable debate about aspects of this period. 

Starts Mon 16th September  for 10 weeks (not 28th Oct nor 4th Nov nor 2nd Dec), until 9th December   Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays.

Building a volcano.  Jon Blundy,   University of Bristol

The 2019-2020 monthly Tuesday evening lecture series in the School of Earth and Ocean Sciences will be held in the Wallace Lecture Theatre (0.13), Main Building, Cardiff University, Park Place,
 Cardiff CF10 3AT.  Lectures begin at 18.30.  Booking is not needed.  Should you require the Q&A sessions to be in Welsh, please email edwardsd2@cardiff.ac.uk at least two weeks before the event.

Did you know that the majority of volcanic eruptions – maybe even 90% – occur under water and of which we are largely unaware? There remains a very great deal we don't know about volcanoes, but many exciting new insights are emerging from ongoing research. This lecture series will encompass the diversity of volcanoes, their functioning and products, together with the nature of eruptions and their attendant problems of predictions plus their ensuing past and present environmental and biological impacts.

My big prize!

My Big Prize!

Someone has asked why I was at last Saturday's Festival of Geology. The answer is that I was collecting first prize in the Photo Competition. £100, thank you very much! The photo is of Banded Iron Formation, taken in August 2013, while I was in Karajini National Park, Western Australia. If you wish you can download it from HERE. Or, even better, buy the GA calendar 2020 HERE and look at October. 

You may have seen my photo in various other places. It has been used on a book cover, blogs (THIS ONE at 4:35mins), and in lectures. This is with my permission, as they acknowledge that it is my photo (mostly).

Banded Iron Formation (BIF) rocks mark a change in the Earth's atmosphere. Single-celled creatures in the oceans started producing oxygen as a waste product. This reacted with dissolved iron, producing rust, which fell to the sea floor to form BIFs. When the iron was used up the oxygen moved into the atmosphere. (This is a somewhat simplified version!)

The prize winning photo


I rather like this one, taken not very far from the previous one. You can get it HERE.

Beyond Extinction - Lecture

BRLSI Lecture by Wolfgang Grulke

A correspondent has informed me that Wolfgang Grulke will be giving a lecture based on his forthcoming book "BEYOND EXTINCTION". You can find out about the author's collecting life HERE, and his business career HERE.


You can book a ticket (£10) HERE, BUT the author has written to me to say:-

For the Bath event there is a booking fee of £10 online, in return for a £20 discount on any of the books.

Siberian Traps - and More!

The Most Devastating Volcanic Eruption

A corespondent has brought THIS VIDEO to my attention. It is all about the Siberian traps and other Large Igneous Provinces (LIPs) and the consequences for the world. I am not sure whether to be depressed by the horrific consequences or optimistic because what is happening now is not as bad - at least, not yet.

There is a SECOND PART concerning the causes of these vast eruptions - mantle plumes.

There is a vast amount of information within the videos and they are well worth watching. A tip - turn off the subtitles, they often hide information on the screen.
