Thanks Walt manofglass for the heads up on this. www-m.cnn.com/2019/02/01/americas/meteorite-cuba/index.htmlA suspected meteorite is shown in the western Cuban town of Viñales on Friday. Havana, Cuba (CNN)A meteor broke apart over western Cuba on Friday, hurtling numerous pieces of various sizes to the ground in several towns in Pinar del Rio province, the state-run Granma newspaper reported. One meteorite landed with a "loud explosion" in the town of Viñales, Granma said. Researchers from several Cuban agencies, including the Institute of Geophysics and Astronomy, confirmed the meteorite strikes, Granma reported. There were no reports of any injuries. The US National Weather Service began tweeting about the event Friday afternoon, eventually saying that radar may have detected the meteor at 1:21 p.m. ET at an altitude of about 26,000 feet.

Except for the fusion crust on the outside, this looks like a plain old rock you could pick up just about anywhere.

Does not look like a very typical meteorite to me.

Looks like a stony meteorite now that you mention it, they do come in several forms !

I would have expected the heat from passing through the atmosphere to have fused the rock into a more homogenous mass.

If that would have been a piece of stony meteorite the main body would have popped when it entered the atmosphere from being heated rapidly from being cold as crap traveling thru space for a long time. I imagine the fragments might glaze over slightly during their decent depending on what angle and distance traveled after the first blow up happened ! That piece appears to have a glaze or patina of sorts on it. Rock (WILL) blow up when heated rapidly as quite a few Flint knappers know !
Myself included !

Scientists have only three classifications for meteorites, but in reality they come in every variety imaginable. The recent explosion over Cuba happened shortly before landing so the fragments only had a short exposure to our atmosphere.

Hadn't thought of that. Need more coffee to get the old brain goin'.

That is a stony meteorite, but I doubt the one in the photo is from the recent fall. The fusion crust looks too old and weathered. A recent fusion crust would be more complete and dark black.

Does not look like a very typical meteorite to me. There are many types of meteorites. That is definitely a meteorite.
You may be used to seeing iron meteorites like this one:
But stony meteorites look different such as this one:

The recent explosion over Cuba happened shortly before landing so the fragments only had a short exposure to our atmosphere. There are three primary classifications iron, stony and stony iron. But there are numerous subclassifications such as octahedrites and plessitic irons, common chondrites, carbonaceous chondrites, howardites, etc. in stone meteorites and pallasites and mesosiderites under stony irons. These are just a few examples.

I am used to some which do not look like your fist photo. Love the second photo. thanks for educating me.

A couple of years ago I found a rock on my place that I thought for sure was a weathered meteorite - extra heavy, remnant crust, ferromagnetic, and metallic reflection in a window I cut. I sent a sample to a local meteorite club member who had a friend test it. Results said it was terrestrial. Haven't been that disappointed since my brother tried to tell me Santa Clause wasn't real... I still don't want to believe either of them.

I sent a sample to a local meteorite club member who had a friend test it. Results said it was terrestrial. Haven't been that disappointed since my brother tried to tell me Santa Clause wasn't real... I still don't want to believe either of them. I had one stone that I found loaded with olivine crystal and tested positive for nickel. Also tested it for magnetism and it was clearly magnetic. I sent a big chunk off to a well known meteorite hunter to get his opinion. Did not hear from him in a while so I wrote to him. He claimed it was not magnetic, which is the first thing I checked and it was definitely magnetic, and said he threw away the sample instead of asking me if I wanted it back. I was so pissed.
I have another sample at a lab overseas. Last I heard they asked if they could do an oxygen isotope analysis on it, which is only done on rare confirmed meteorites due to the cost and time involved. They sent it to a local university for the test, but their own samples get priority so it was sitting in limbo. Been there for about 12 years or so now. I need to contact them again one of these days and see if they ever came to a conclusion. A meteorite dealer I took it to in Southern California said it looked like a martian meteorite. It does have martian and angrite meteorite properties.
Identifying meteorites can be challenging sometimes.

That's one cool collection, vegasjames! Thanks. Used to have a lot more posted on here but those were uploaded on my Photobucket. When Photobucket got suddenly very greedy I deleted all the photos on my account since they would not allow them to be viewed unless you paid their ransom. Those are just some of my favorites because they look like other things. You can see a seal in one, a bird skull, a falcon, a horse head, a crow, etc if you look carefully at them.

Wow, vegasjames, I can only imagine how mad that would have made me. As for the test, I'd read that university labs took a long time but I never would have thought it would take 12 years! After years without any luck it was just part of my routine to check likely looking rocks with a magnet. I nearly peed my pants when the magnet clicked onto the side of that rock and stuck. The person that helped me out knew another collector who was a buyer and had plans to meet him at an upcoming show. He said the pictures looked promising, so I mailed him a sample. The buyer had a gun-type instrument that could analyze the nickel content. The rest you know. I still keep an eye out and a magnet in my rock bag...
