Dr. Richman discovered ET fat cells

Also, lipid doplets don't usually contain hemoglobin.

That's not what the caption says. You are jumping to conclusions again.

You slinged mud and jumped to conclusion without studying anatomy of fat cells:

Actually, all I did is point out that your thread title misrepresents what Dr. Richman actually said (and meant).

Rectified version:
Fat cells found in “presolar” meteorite

Dr. Dan Richman discovered lipids in meteorite Murchison as shown in Fig. 8 at
http://astrobiology.jhu.edu/wp-content/uploads/2011/02/2011-2-2-prebioticlipidsintro1.pdf

However, the lipids are in fact fossilized fat cells as labeled at

White fat cells (adipocytes) contain a single lipid droplet surrounded by cytoplasm, as shown in these images:

Fat cells differ from red blood cells in that fat cells can have different sizes in an animal while red blood cells have same size in an animal.

Geological vesicles show no concentric circles, especially the central dark circle marked with green line in Fig. 1 above.

No they're not.

You make a claim which is not supported by your original link, then you provide another link which declares that this is pre-biotic matter, which you then attempt to warp with more of your personal idiocy from that pathetic wretch-fossil blog. It's no wonder you are not taken seriously here.

That's not what the caption under his photograph says.

Well, the significant thing is that he is saying that vesicles "could" from, not that any were found in a meteorite. There is nothing there about fat cells--nothing there about cells at all--coming from meteorites. This boy is desparate.

He's also flooded the internet blogs with copies of his "report". Very weird.

Added : Lipid droplets have no membranes

The following images show lipid droplets have no membranes no matter they are in a fat cell or not:

He's probably one of those types who believe that if you say something often enough and loudly enough, it becomes true.

Whatever Dr. Richman said, I identified them as fat cell remains.

Who give a flyin' f*ck what you identified. You have no credentials and zero credibility.

I still believe that bewildered's main purpose is to sell meteorite fragments on the internet.

Very creative of you.

Maybe so. But he's constructed an extravagant story as a sales pitch.

On the other hand, people sell things of even less value to rubes all the time (ionic bracelets, magnetic insoles for shoes, astrology books, etc), so if he can make money at this, good for him.

Cytoplasm of ET fat cells

The dark rinds marked with red lines in Fig. 1
( Edit [Moderator]: Link removed ) must be cytoplasm of ET fat cells instead of membranes or artifacts. The dark rinds are over one micron in thickness. Membranes of cells and organelles are less than ten nanometers in thickness (see http://www.answers.com/topic/how-thick-is-the-plasma-membrane).

The dark rinds in Fig. 1 cannot be artifacts as they do not appear in the smaller spheres in the same image. Those smaller spheres are small lipid droplets that have seeped out of the bigger lipid droplets contained by the fat cells.

By the way, the following micrographs clearly show lipid droplets cannot have membranes of 1-micron in thickness:
