Last year, after learning that the substance was once used as a pigment, I decided to try and make my own paint. Verdigris is a green corrosion often found on old pins within entomology collections (as well as elsewhere, on things like statues and copper pipes). You may remember her amazing moth illustrations created with deposits of verdigris on pinned insects and she’s now using that technique to explore Museum staff’s favourite insect specimens. She is also an artist and has been trying out innovative techniques for her paintings. Katherine Child, image technician in the Museum’s Life collections, doesn’t just use photography to capture the beauty of specimens.

Either way, some reassessment of the palaeobiology of these unique organisms is certainly required! The discovery of the filaments means that we have to reconsider how we define an individual rangeomorph, and may help us understand how rangeomorphs (seemingly) rapidly colonised deep-sea environments. It is possible that these filaments were involved in clonal reproduction, like strawberry plants today, but they may have had additional functions such as sharing nutrients or providing stability in strong ocean currents. We find that this species of rangeomorph can be connected to each other over meters! Photo: Alex Liu. An undescribed rangeomorph fossil with filamentous connections at the base of the frond. We found that fine filamentous threads connect rangeomorph fronds of the same species, in some cases over many meters, though they are typically between two and 40 centimetres long. In order to better understand them, my co-author Alex Liu and I travelled to Newfoundland, Canada to explore the rocks which host these remarkable fossils and over the past few years we have made an unexpected discovery. The UNESCO world heritage site Mistaken Point in Newfoundland, Canada, is one of the sites on which we find exceptionally preserved rangeomorph fossils. Given all this, it may not be a surprise to hear that we know relatively little about how these organisms made their living and came to dominate the ancient seafloors. However, they lived at such a remote time in Earth’s history that they do not possess any direct living descendants. There is no evidence to suggest that rangeomorphs were able to move around, rather, they lived stuck to the sea floor in the deep ocean, far below the reach of light.ĭespite this strange set of characters, there is growing consensus that rangeomorphs likely represent very ancient records of animal life. The smallest known rangeomorphs are less than a centimetre in length, but they grew huge and the largest records indicate they could stand more than two metres tall. This arrangement appears to maximise the surface-area to volume ratio of the organism, rather like a lung or a gill would today. Rangeomorphs are characterised by a strange frondose branching anatomy, where large primary branches host smaller branches which themselves host smaller branches again. I HOPE THAT WHAT I PRODUCE, WILL HELP TO ACHIEVE THIS POINT IN QUALITY I CREATE PASTE UP IMAGES AND THESE ARE ADAPTED INTO COLLAGES OR JUST PICTURE IMAGES, SOME ARE READY FOR PRINT.Some of the very oldest complex, macroscopic communities on Earth appear in the fossil record about 570 million years ago and record the presence of a group of organisms – the rangeomorphs – with an unfamiliar body plan that, at their ultimate extinction, was lost from life’s repertoire. FROM THE START OF YOUR COLLECTED ART TO THE MANY YEARS THAT GO BY ,THE CONTENTMENT SHOULD REMAIN ABSOLUTE. A COLLECTION OF ART ,THAT ONE HAS ASSEMBLED, SHOULD GIVE PLEASURE AND A CONTENTED FEEL OF SATISFACTION FOR LIFE. I AM COMPLETELY SURROUNDED WITH FINISHED CANVASES, BOOKS,PICTURES,ALL THE VISUAL ASPECTS OF ART,THIS KEEPS ME IN A BUBBLE OF TOTAL CONTENTMENT.AS I HAVE RETIRED I CAN AFFORD THIS TOTAL IMMERSION OF VISUAL DELIGHT. IT MIGHT BE OIL PAINTING,ACRYLICS, LINO PRINT, A PASTE UP IMAGES,SCULPTURE CLAY WHEN I AM INCLINED. MY STUDIO IS IN A STD GARAGE ,AND I CREATE ART ,SUBJECT TO WHAT MEDIUM I USE. I PRODUCE ART EVERY DAY,IT MIGHT LEND TO AN OIL PAINTING, OR A DESIGN FOR A GARMENT PRINT IN FASHION.ALSO LINO PRINTING. A COMPLETE WRITE UP OF ME IN RELATION TO ART ,HAS BEEN SUBMITTED ON ,EACH COLLECTION SITE PLEASE VIEW THE SUMMERY ,AS IT EXPRESS HOW I VIEW THE ART AND LIFE ART IS WHAT I TRY TO ACHIEVE, THE QUESTION OF HOW GOOD THE ART IS, THEN ONLY THE INDIVIDUAL CAN SAY.
