A Field Trip To Granton Quarry

Recommended Posts

njfossilhunter

Fossildude19, JefferyP, fossilsofnj and I went to Granton Quarry in North Bergen NJ to collect in the Lockatong Fm for Triassic fish. We had a great time and we all found some interesting specimens to add to our collections While the others were hard at work I came across a rather interesting flatten oval shaped sediment between two layers of the black shale in a small area I was working and at first I really didn't pay to much attention to it until one of them broke apart and I noticed that they seemed to be filled with tiny fish bones. I took the sections of slabs home and two days later took them to the NJSM to have someone look at them and one gentlemen told me that they maybe coprolites....interesting. As I was cleaning them up one of the other oval's flaked off exposing a fish tail and I was also able to expose another one without breaking apart.  

 

As you can see the two right section of slabs go on top of each other and the one to the far left slides into the middle slab. No 1 you can see a fish tale and No 1a was laying right next to it but don't seem to be a extension to the tail section when I slit this section apart in the field No 1a became exposed while No 1 remained intact until I got it home... No 1b are the pieces that cover No 1 and No 2 I also exposed without it breaking apart I'm going to leave these as is and when it dries out I will cover it with some type of stabilizer.

 

In the second picture I have another fish that don't have the head attached. When I exposed it ,,it did appear to have the same matrix covering the specimen. Now the funny part about all this is that I never had come across this before while search for fish in this layer.

 

Any Insight would be greatly appreciated.

Do you have close ups of 1a and 1c? Very interesting piece. More likely a concretion than a coprolite. Congratulations and thanks for posting.

I've got some like this too, Tony, ... from previous trips.

I'm thinking it is some sort of preservation in a nodule- something covered the fish and caused some sort of nodule to form around it.

Some taphonomic process. 

I'm leaning away from coprolite as well.

 

I will try to get pics up this weekend.

NICE.....Fish Tim . The first one looks to be complete...I guess with a little prepping you can expose more of it.

Thank you, gentlemen. I'm hoping it's complete.   :fingerscrossed:

I'll post more as I clean up the shale I brought home. ;) 

Regards,  

 

 

EDIT: By the way, Tony, ... 1a looks like a skull to me - maybe the fish folded over itself when it hit the bottom.

Very cool, in my opinion.

Thanks Jim! I will probably give it a shot at some point. 

I need to practice with some of this material first, ... before I give it a go, however. ;)

I was wondering about 1a and It never ocurred to me  it maybe a fish skull. Thanks Tim....I'm going to see if I could maybe place 1a in front of 1 to see if its a match's up and I'll take some pic's and post them for you to determine if this is the case.....Thanks again Tim....You have always been a big help with this stuff.....:SlapHands:
