Rank Amateur Posted December 7, 2017 Share Posted December 7, 2017 Sorry, another fossil from my dead acquaintance's estate. This is an interesting fish in a geode-like rock. Open it up and you can see the top and the bottom of the fish's image. The person who split open the rock did an excellent job. The seam is sharp and tight. To get to the fish inside: It is about 10½ millimeters centimeters long and 4¾ mm wide/tall at its widest point. I did just a little bit of magic in this picture to heighten the image. I made it a little bit darker and heightened contrast just a little. The rock from the outside looks like a sweet potato. In fact, the inside of the rock has a reddish, sweet-potato coloring though where the ghost image of the fish is, it is grayish brown. I don't know where this fish was found. A nice fish, well-preserved by my eye. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted December 7, 2017 Share Posted December 7, 2017 This is a fossil fish in a concretion. I’m not an expert in these but maybe from the Triassic of Madagascar. It is well preserved, it’s called “lagerstätte”. Amazing things these are. maybe @oilshale would know more. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
abyssunder Posted December 7, 2017 Share Posted December 7, 2017 It's not a geode, but a nice nodule with a fossil fish encased. Maybe it's from Argentina.

abyssunder Posted December 7, 2017 Share Posted December 7, 2017 Yes, that's what I'm trying to correct. 1 " 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.

fossilized6s Posted December 7, 2017 Share Posted December 7, 2017 Definitely a nice fish nodule from Madagascar or China, leaning more towards China given the preservation.

abyssunder Posted December 7, 2017 Share Posted December 7, 2017 (edited) Then it might be a Perleidus sp. ?

Fossildude19 Posted December 8, 2017 Share Posted December 8, 2017 Definitely from Madagascar - and possibly Perliedus madagascarensis, ... but another possibility is Boreosomus gillioti. Maybe @oilshale will have a more solid ID. Nice fossil.

piranha Posted December 8, 2017 Share Posted December 8, 2017 Perleidus from the lower Triassic of Madagascar has recently been assigned to the new genus: Teffichthys Marramà, G., Lombardo, C., Tintori, A., & Carnevale, G. (2017) Redescription of ‘Perleidus’ (Osteichthyes, Actinopterygii) from the early Triassic of northwestern Madagascar.

oilshale Posted December 8, 2017 Share Posted December 8, 2017 Piranha is right, it's a Teffichthys madagascariensis from the Early Triassic of Madagascar. The other fish in abyssunder's post is from the Early Triassic, Lower Qinglong Formation which is exposed at Qingshan Quarry, Jurong, Jiangsu Province of China. This fish is often sold under the name 'Lepidotes jurongensis'. In 2009, the fish was described by Li: A new parasemionotid-like fish from the lower triassic of Jurong, Jiangsu province, South China, Palaeontology 52(2):369 - 384 as Peia jurongensis. Thomas PS: Nice fish btw! 3 Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC). Link to comment Share on other sites More sharing options...
FossilDAWG Posted December 8, 2017 Share Posted December 8, 2017 Very nice fish! Just for clarification, is it really only 10 1/2 millimeters (less that 1/2 an inch) long? That seems very tiny for this species. Don 1 Link to comment Share on other sites More sharing options...
abyssunder Posted December 9, 2017 Share Posted December 9, 2017 I assumed that the dimensions were given wrong, they should have been ten times bigger to fit, but if the support for the nodule is Granite than the measurments might be good and there is a professional photo. Hope we'll find out soon. Meantime, here is the document mentioned by Thomas, if someone needed it: Q. Li. 2009.

Rank Amateur Posted December 10, 2017 Author Share Posted December 10, 2017 My mistake: the measurements. I said millimeters when I should have said centimeters. I was brought up on feet and inches. I was rooting years ago when we were considering changing to metrics. Link to comment Share on other sites More sharing options...
