Fossils found during my childhood, never succeeded in identifying them

[bobby_Pendragon]

Hello everybody,

 

I found many fossils when I was a child, and I never managed to identify some of them. It has been puzzling me for many, many years.

I would be very thankful if someone could help me find out what these are and help me solve this mystery!

 

 

The three unidentified fossils below have been found in the Minganie Regional County Municipality, Québec, Canada. They come from the Ordovician-Silurian period, at the boundary between the two periods I believe. The region is extremely rich in fossils.

 

1.

Is it a tooth, a shelled mollusk, or something else?

It does not look like a shark tooth, or any mollusk I know.

 

 

2. 

I am not even sure if this is a fossil, but it looks like a tree trunk...

 

 

 

 

3. No idea what this is... Maybe the shell of a mollusk halfway visible?

 

 

Thank you!

Welcome the forum!

Unfortunately, the pictures are broken and do not show for us. You may have to try to reupload them.

snarge, sorry about that, I'm so bad at this.

 

1. First group of pictures:

 Welcome to the Forum.  

Your item is a Rugose coral.

+1 with Rugose Coral

Wow thank you Fossildude19, it is exactly that! Did not expect to get a reply so quick.

 

2. Second group of pictures: I was certain that it was tree trunk in the past, but now I realize that it is probably something less extreme.

Part of an orthoconic nautiloid.

...But still very exiting!

3. Last group of pictures: I thought it was a worm when I was a kid, but I now think that it is a shell that is half visible:

 

 

These are my last pictures, sorry again for the broken links to the pictures beforehand. You are very helpful!

 

Merci,

To Tidgy's Dad:

 

I had doubts that it could be an orthocone, but the ones that I have found all have intervals of lines or ridges (like in your picture above), while mine has a very smooth surface. Maybe it is a different specie of orthoconic nautiloid?

 

Thank you!

Merci,

Looks like it might be a partial harpid trilobite, preserved similarly to the below pic, just without the body, glabella and eyes. Maybe @piranha could confirm this?

Was thinking the same thing. 

[Fossildude19]

I took the liberty of cropping, enlarging, and contrasting one of the last photos.

More likely a Hibbertia (?).... And it seems to be the lower shell of the "Siebsaum"  (sorry, I'm missing the correct english term)

Siebsaum in this instance would roughly translate to the cephalic fringe/brim, or preglabellar field (that somewhat resembles a screen or sieve on the harpetids). This image is from Sam Gon III's excellent site on trilobites:

The first item is a rugose coral as several people said.  Given the age and locality it is likely to be either Streptelasma or Lambeophyllum.  Confident identification usually requires thin sections or cut and polished cross sections, but since the specimen is worn it is possible a top view might show useful details.

 

The second specimen is an orthoconic nautiloid, as several people said.  It is probably the siphuncle of an Endoceras or a related genus.  These siphuncle are large and robust, and often survive when the more delicate chambers (camerae) do not.  

 

The third specimen is certainly the fringe of a harpid trilobite.  Dolichoharpes and Hibbertia occur in the area (Shaw & Bolton 2011.  Ordovician trilobites from the Romaine and Mingan formations (Ibexian- late Whiterockian), Mingan Islands, Quebec. Journal of Paleontology 85: 406-441.)

Thank you so much for all the replies, I never expected to have all my fossils identified so quickly.

 

The third picture is probably a trilobyte as you are saying!

 

Thank you again,
