We are lucky to have birds!

The K-Pg Event Almost Killed the Birds

In this article a researcher from Bath University says that only a small number of ancestral bird species survived the asteroid impact that did for the dinosaurs.

All the tree living ones died; probably because all the trees were destroyed! Only five bird lineages survived and they were all ground dwellers.  There is a lot more in the original paper, but this is far from my (limited) areas of expertise so I will leave criticism of the evidence to others.

The tinamous is one of the most similar living birds to those that survived the K-Pg. Daniel J Field, Author provided

Dave Green - Planetary Geology
When
Mon, 21 May, 19:30 – 21:30
Description
Planetary Geology. Monday 16th April, for 10 weeks, until 9th July (not 7th nor 28th May). The state of knowledge of the planets of the solar system has improved vastly in the past 40 years as a result of space missions and improved technology for observation and analysis. The course will examine the results of this activity and evidence for these interpretations in terms of the internal structure, magnetism and geophysics of these bodies; their tectonics and volcanism, the effects of impacting bodies, and the surface conditions –atmospheres, oceans, sedimentary features and biology. Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays. Cost £70.

Dave Green, Field Course: The Geology of Western Norway
When
25 May – 4 Jun 2018
Where
Western Norway (map)
Description
Field Course: The Geology of Western Norway Dates will be for a week to 10 days around a period from May 25th to June 4th. At this stage I envisage a two, or three base trip, including the Nordfjord, Trondhjeim and Lofoten areas, to study basement of Archaean and Proterozoic age, the trans-Scandinavian intrusive belt, Caledonian nappes, mineralisation and of course, glaciers and the fantastic fjord scenery.

Archaeopteryx yet again

Archaeopteryx Studies (Continued)

The question on everyone's lips - "was Archaeopteryx capable of flying" - has been answered positively; at least to the satisfaction of the authors of THIS PAPER.

More accessible versions can be found HERE and HERE. Because Archaeopteryx fossils are so precious, non-destructive methods have to be used and the latest is the European synchroton in Grenoble. There, researchers found Archaeopteryx bones most resembled those of pheasants - birds that occasionally use active flight to cross barriers or dodge predators.

There is a lot more about it in the papers, especially the Nature one. I will leave you to read them all at your leisure.

Information on Kilauea eruptions

Information on Kilauea eruptions

Information can be difficult to get about the current volcanic activity on the Big Island in Hawaii. THIS ARTICLE has a good introduction to the activity and has lots of links to a multitude of information. I especially liked THIS one. Click on the photos to get the BIG picture!


Healing crystals

Tempted to get "Healing Crystals"? - Read This

I got my geology degree from Aberdeen when Professor T. C. Phemister was in charge and therefore I had four years of mineralogy and crystallography. 

I don't think the health giving properties of crystals were mentioned once. 

We were told to keep the asbestos in its glass box and not to lick our fingers when we were looking at arsenic. Not a great deal more on the health front.

But now you are probably aware that many crystalline substances are sold for their healing properties. HOW they heal is never mentioned.

I you are tempted to buy, read this article first. It discusses the ecological damage their mining causes and also the exploitation of miners and child miners. This does not appear on the sales pitch. 

There are many good reasons to look at crystals. I don't think health is high on the list.
