Super Sharing Saturday – Science and Nature

A science based post, with some work related pictures and a link to an online catalogue at the end.

INTRODUCTION

Welcome to the next post in this series of sharing posts. Our theme in this one is nature, and while most of the pieces I am linking to are about the present, we being with a journey back to…

385 MILLION YEARS AGO

This was when our ancestors first moved from the sea to the land. The usual reckoning is that the key development that led to this happening was to do with limbs, which would seem to be common sense. However, according to this piece on astrobio.net, there is an alternative view now being proposed that the key development was actually to do with vision not limbs. As is now my custom I am using an image to link to the full article:

Now we move back to the present, and we start with a distressing story about…

RHINO POACHING

As wild rhino numbers continue to decline the poachers whose activities are most directly responsible for this decline are becoming more brazen. This story concerns a Rhino in a zoo which was shot for its horn. The saddest aspect of this story is that the wealthy Chinese who buy most rhino horns do so based on alleged properties of the substance that are entirely fictional – this is the same stuff that our own finger nails are made of, and no one would pay big money for those. As usual, the link is in the accompanying image.

IMAGING UNDER WAY FOR APRIL AUCTION

INTRODUCTION

A few of the images that feature in today’s post were done on Tuesday, most today. All are of items that will be going under the hammer on April 27th. We aim to have our catalogues ready about one month before the sale, which with a two-day sale coming up on the 30th and 31st effectively means that I have tomorrow and next week at my disposal for imaging.

A WIDE RANGE OF IMAGES

I will start with the images from Tuesday that I considered worth sharing…

206
Heptagonal coins are of course commonplace in this country – heptagonal medals less so.

Close ups of each face of lot 206

Today’s images cover a wide range of interests, and I will deal with the best of them by category…

MILITARIA

These items are in 250s to low 300s, so will go under the hammer near the end of the second hour of the auction…

Next up in today’s whistle stop tour are some bulk postcard lots…

To finish, some interesting miscellaneous items…
