Recently found some well preserved stems in the shinarump formation of Utah which I believe to be Lyssoxylon. There seems to be evidence that these plants were reproducing vegetably. Also there is evidence these plant stems were branching dichotomously. There is some mention in the past of extinct cycads branching but nowhere do I find evidence of vegetative reproduction of extinct cycads. Extant cycads are well known for vegetative reproduction and these pieces are called puppies. (bulbils) So, my question is how does one get a these phenomena into the fossil record? The first pic is detached bulbil alongside from where it seems to have detached from. Second pic is another view of detachment point. Third is bottom of stem and bulbil. Forth is bottom of bulbil. Fifth is top of bulbil seeming to starting to form an apical meristem. Last photo is a more mature bulbil with tap roots growing straight down.

This is a little bit out of my range for age and location, but a friend of mine was asking if this coral he has could be identified. He is a mineral collector, got this in a collection purchase, and the only info he has for this piece was that it came out of Florida. I know it's not much to go on, but I'm hoping it's distinctive enough to get a possible ID and age. Thanks in advance

this was found in deer lake pa on a large piece of shale. whatever these things are they are over 12 inches long, branching and 1/2 to 3/4 inch in diameter. occasionally they appear to have straight vertical lines on the surface. I could see this pattern in only one or two places and could not get a clear photo. Help would be appreciated.

Hello. Been a minute, but I found this rock in my sister's yard in Sylvania, Ohio. I've not a clue what it could be. I've looked up common fossils for the area and I'm not finding anything, so wondering if it's an odd looking mineral. I really don't have anything else to go on, wish I had more info for ya. Any help much appreciated.

From the album: Penn_Dixie_Quarry_Blasdell_New_York
This is some form of coral, most likely branching. -
On the way back from Tully NY, we stopped briefly to look at a roadcut about 45 miles south of Tully - the shale is grey and exceptionally hard. Didn't find any distinct smaller fossils, everything seemed indistinct and not well defined - I turned over a block of shale and discovered a "large branching fossil" that is 15 inches long. Part of the main stem is broken off horizontally along the stem. I outlined the shape in image 1.4 with a black broken line. This is our largest fossil to-date and was an unexpected discovery. UPDATE (7/15): The consensus is that this is the filled in "burrow" of some Devonian creature. Hm. What creature makes burrows this large and extensive? We are more intrigued than ever since this was a quick find during a 5 minute stop at a road cut.
