triopslord Posted December 23, 2015 Author Share Posted December 23, 2015 continuing both unknown location this is a slab with fossils in it i doubt this is id able and this is the last one i am pretty sure it may just be large crystals formed in a rock but once again worth a check Link to comment Share on other sites More sharing options...
abyssunder Posted December 23, 2015 Share Posted December 23, 2015 The last one is igneous rock, a porphyry, and probably the previous one (with the snowflake crystals) also. The larger crystals (larger than the grains of the rock groundmass) are called phenocrysts. https://www.google.com/search?q=igneous+rocks&biw=1360&bih=612&source=lnms&tbm=isch&sa=X&sqi=2&ved=0ahUKEwjxiJjfyvHJAhXCDg8KHbR2CYkQ_AUIBigB#tbm=isch&q=porphyry+rock&imgrc=_ " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Rockwood Posted December 23, 2015 Share Posted December 23, 2015 You might want consider Isognomen for this shape. Here is a shot of an articulated specimen and the ligament attachment sites for comparison. Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 23, 2015 Share Posted December 23, 2015 Your first item looks like a broken chert or flint nodule.

Guguita2104 Posted December 23, 2015 Share Posted December 23, 2015 In the seventh photo I see clearly an Isognomon sp. They are pretty common in Portuguese Jurassic beaches. Link to comment Share on other sites More sharing options...
triopslord Posted December 24, 2015 Author Share Posted December 24, 2015 thank you all for your responses! and i figured the last one was just an igneous rock with crystals but as i said i am still new to identifying fossils. i hope to get more someday to learn about them.
