The rock is from Morocco, which chiking HCL was a positive effect. any information about the age.
Is this a coral colony?
Hakima:
No, Fossils including corals are not to be seen. Looks like aggregate of Calcite (CaCO3) crystals.

many thinks for your time and for your interest!

..yes..I agree with Syed Sir..But sir it apperently looking like fragment of ammonoids.
Susheel:
What features of Ammonoid do you see in this rock fragment?

Syed
Susheel,
Why you said that it looks like a fragment of ammonoids?

Som,
Thank you so much for your answer,
Yes, it looks like a rock fragment, but i don't know why Dr.Susheel guess a fragment of ammonoids?!
Many thanks for your time and interest.

I agree on this is not a fossil. It is of inorganic origin
Maria Luisa,
According to all answers, it is a rock fragment. As Dr. Syed said it is probably a aggregate of Calcite (CaCO3) crystals.
Many thanks for your time and interest.

It is difficult to be certain from photos alone, but there are features that suggest to me that it is a tabulate coral of the Favositina. Compare with that taxon.
George,
Tabulate coral, i think it before, but according to all suggestion by the colleagues, i changed my mind to aggregate of Calcite (CaCO3) crystals.
When i compair this rock with the picture of the tabulate coral, the similarities are very strong. So i think you could be true.
Many thanks for your time and interest.

I came to the discussion late, but I agree with Dr. Engelmann. It seems to be a tabulate coral belonging to the Favositina. It shows different sections of polygonal corallites and in the low-middle part of the first picture some longitudinal sections with tabulae can be seen.
George et al.:
The resemblance with coral Favositina is just superficial.

Sergio,
I think you have true, It looks like a tabulate coral belonging to the Favositina.
Syed,
When i reexamined the specimen, i found that the resemblance with coral Favositina are very strong. So i think that they have true for coral Favositina.
Regards,
Hakima
Hakima:
Would you kindly upload a picture of Favositina with which you match your specimen.

Syed
Hi Syed,
these are some pictures with which i match my specimen. What do you think?
Perhaps the pictures of my specimen are not so clear..! But i will take another this afternoon, hope it helps to convince you.

Hakima:
Unfortunately, none of these pictures convince me. Why don't you cut a section of your specimen to show the features, if any, of the last documented specimen. Did you collect your specimen from Palaeozoic rocks or not? Next time when you document a fossil specimen, its locality, lithology, stratigraphic level and associated fauna and flora, if any, must be furnished to attempt realistic and reliable identification.

Syed
Syed,
When i cut a section of this specimen i will tell you of the result.
